No VPL knickers: the quick answer
What stops VPL is three things together: no raised edge across your seat, an edge that sits where your clothes are not pulled tight, and a colour close to your skin. Flissie women's bamboo boxer shorts (we make them) are our pick under jeans, leggings and everyday trousers: no seam across the back or sides, so there is no edge across your seat, a buttery soft 6 inch leg that ends on the thigh and stays put, and two nude shades, taupe white and chocolate brown.
- Fitted dress or sheer fabric: a bonded seamless knicker, such as sloggi's ZERO Feel Hipster, £13 or 3 for £30, with free-cut edges and dot bonding.
- The lowest price per pair: M&S Body Invisibles No VPL High Rise Knicker Shorts, £14 for 3, or Uniqlo's AIRism Ultra Seamless Shorts at £7.90.
- Seamfree, in viscose from bamboo: Boody's Boyleg Briefs at £13, or its 6 inch Seamfree Undershort at £18, in UK 6 to 22.
- Thighs rub as well as VPL: Flissie women's bamboo boxer shorts (we make them, our pick), with no seam across the back or sides and a 6 or 9 inch leg, £13.50 a pair or £11.50 a pair in a 10 pack, in UK 8 to 30.
- Running: Runderwear's seamless Women's Running Briefs, £18, or its 8 inch long boxer, £23.

VPL meaning: what it actually stands for
VPL stands for visible panty line. It is the outline of your knickers showing through your clothes, usually across the back of the thigh or the seat, and most often under something fitted, thin or light-coloured.
It has nothing to do with how much underwear you are wearing. A thong can show. A full brief can be invisible. What decides it is where the edges sit, how thick they are, and what is on top.
What actually causes VPL
Four things, in order of how much they matter.
1. The seam or hem. A raised, stitched edge is a ridge, and under fitted fabric a ridge shows. Flat, bonded or seam-free edges sit almost level with the fabric and mostly do not. This is the whole idea behind seamless knickers.
2. Where the edge lands. An edge that cuts straight across the fullest part of your bottom will show. One that sits under the curve, or well below it, usually will not. This is why a longer leg often disappears where a brief does not, and why a seam at the front matters far less than a seam at the back.
3. What you are wearing on top. Thin, light, stretchy and pale all make it worse. White trousers are the hardest test in fashion. A thick, dark, structured fabric hides almost anything.
4. Colour contrast. Dark pants under light clothing show even when the edges are perfectly flat, because you are seeing the shadow rather than the seam.
Most advice only deals with the first one. That is why people buy no VPL knickers, find they still show under white trousers, and conclude nothing works. The seam is one cause of four.
The brands, compared on seam construction
Seven options people weigh up when they are trying to solve this, compared on how the edges are made. Ours is first and marked; the rest run from the lowest price per pair. Checked on each brand's own UK website, or a UK retailer, on 8 October 2026.
| Brand | How the edges are made | Fabric | Longest leg | Price | If you have worn them |
|---|---|---|---|---|---|
| Flissie women's bamboo boxer shorts (ours) | Seamless back and sides, flat seam at the front | 95% bamboo viscose, 5% elastane | 6 or 9 inch | £13.50, or £11.50 a pair in a 10 pack | 60 days, full refund, worn or not |
| M&S Body Invisibles No VPL High Rise Knicker Shorts | Smooth-cut edges, bonded waist and gusset | Not shown on the M&S pages we could read | Short | £14 for 3 | Not confirmed: the M&S help pages did not load for us |
| Uniqlo AIRism Ultra Seamless Shorts | Seamless, though Uniqlo notes the care label and name tag have seams | 71% polyamide, 29% elastane, cotton crotch | Low-rise hiphugger | £7.90 | Within 30 days, with a £2.95 return fee |
| sloggi ZERO Feel Hipster | Free-cut edges, dot bonding, label-free | 76% polyamide, 24% elastane | Hipster | £13, or 3 for £30 | Free within 30 days, if tried on over your own underwear |
| Boody Boyleg Briefs and Seamfree Undershort | Seamfree: knitted as a tube, so no side seams | 79% viscose from bamboo, 15% nylon, 6% elastane | 6 inch undershort | £13 boyleg, £18 undershort | Comfort Guarantee on your first single pair only |
| Step One Women's Body Shorts | Not published | 95% bamboo viscose, 5% spandex | Not published | £15, with 36 of 40 colours at £9 in its sale | 30 day first pair guarantee; its refund policy says sale items cannot be refunded |
| Runderwear Women's Running Briefs and Long Boxer | 360 degree seamless | 92% recycled polyamide, 8% recycled elastane (long boxer) | 8 inch long boxer | £18 brief, £23 long boxer | No returns once tried on, but a 90 day chafe-free guarantee |
On a phone, swipe the table sideways to see every column.
Boody is the seamfree option in bamboo viscose. Its knickers are knitted as a tube, so there are no side seams, in briefs, bikinis, midis, high waist, g-strings and period underwear, in sizes to 4XL (UK 22). It also makes a 6 inch Seamfree Undershort, at £18, for days when thighs rub as well.
For bonded edges at a lower price, look at sloggi, M&S and Uniqlo. sloggi's ZERO Feel Hipster uses free-cut edges and dot bonding, M&S's Body Invisibles have smooth-cut edges and a bonded waist and gusset, and Uniqlo's AIRism Ultra Seamless Shorts cost £7.90. All three are short, synthetic knickers, which is the trade covered below.
Runderwear are the technical option. 360 degree seamless, and their long boxer runs to 8 inches, so it can help with both problems at once. Two catches: the fabric is fully synthetic, a recycled polyamide, and they do not accept returns on underwear once it has been tried on, although Runderwear's 90 day chafe-free guarantee refunds you if a pair makes you chafe.
Step One do not publish their seam construction or an inseam for the women's Body Shorts. If either is what you are buying on, you are guessing. They are £15 a pair, with most colours at £9 in the sale when we checked.
And us. Flissie women's bamboo boxer shorts have no seam across the back or the sides, which is where the line actually appears, with one flat seam at the front where fabric is not pulled tight. The leg is 6 inches as standard, or 9 inches, the longest here, and it stays put.
The options for no VPL knickers
Fully seamless knickers
Bonded or laser-cut edges with no stitching anywhere. The best answer for very fitted, very sheer fabric, and what most brands mean when they sell seamless underwear.
The trade: almost always synthetic, because bonding needs a fabric that will fuse. That means less breathable. The bonded edge can also start to peel after a lot of washes.
sloggi ZERO Feel Hipster
Best for: a bonded, label-free knicker under fitted, thin fabric
| Price | £13 a pair, or 3 for £30, on sloggi's UK site (8 October 2026), with some colours reduced to just over £9. |
|---|---|
| What you get | A hipster in 76% polyamide and 24% elastane with free-cut edges and dot bonding, label-free, XS to XXL, which sloggi maps to UK 4 to 28. |
| Pros | No stitched edge to show, and a wide size range for a bonded knicker. |
| Cons | Fully synthetic. A short hipster, so no help if thighs rub. Returns only if tried on over your own underwear. UK delivery is £4.99 unless you register. |
M&S Body Invisibles No VPL High Rise Knicker Shorts
Best for: the lowest price per pair, from the high street
| Price | £14 for 3, about £4.67 a pair (8 October 2026). |
|---|---|
| What you get | High-rise knicker shorts with smooth-cut edges, a bonded waist and gusset, and deep sides, in M&S's Flexifit fabric. We could not read the fabric percentages or sizes on M&S's site. |
| Pros | 4.1 out of 5 from 495 reviews. Fuller coverage than a hipster, and easy to buy in store. |
| Cons | A short leg, so no help if thighs rub. Check the fabric and sizes on the label. |
Uniqlo AIRism Ultra Seamless Shorts
Best for: a cheap seamless pair under jeans and trousers
| Price | £7.90 a pair (8 October 2026). Delivery from £3.95, free over £50 or with Click and Collect. |
|---|---|
| What you get | Low-rise hiphugger shorts in 71% polyamide and 29% elastane with a cotton crotch, XS to L. |
| Pros | Uniqlo says the seamless design does not easily show through bottoms. The cheapest single pair here. |
| Cons | Sizes stop at L. Uniqlo notes the care label and name tag have seams. A £2.95 fee on returns. |
Seamless where it shows
No seam across the back or the sides, with a flat seam at the front where fabric is not pulled tight over it.
This is what we make, and it works through placement rather than construction. The line that shows is almost always the one across your seat. Remove that and you have solved the common case, without needing a bonded synthetic against your skin.
The trade: there is still a seam. Under sheer fabric a fully bonded brief will be flatter.
No VPL thongs
A thong removes the edge across the seat entirely, so there is nothing to show. It is the traditional answer and it still works.
The trade: less coverage, no protection where thighs touch, and not everyone finds a thong comfortable for a full day. A no VPL thong still has a waistband, which can show under something very fitted and high-waisted.
No VPL full briefs, cut high
A full brief cut high on the hip puts the leg opening above the fullest part of the thigh, where clothing is looser.
The trade: the leg elastic can dig, and under a very fitted skirt the waistband can still show.
Longer legs
A 6 to 9 inch leg puts the hem well down the thigh, below the curve, where fabric is not stretched tight over it.
The trade: it is a bigger garment, and a wide waistband can show under something very fitted. It is also the only option on this list that covers the thighs, so they glide instead of rubbing.
Boody Seamfree Undershort and Boyleg Briefs
Best for: seamfree bamboo viscose, with a 6 inch leg if thighs rub, in UK 6 to 22
| Price | £18 for the 6 inch Seamfree Undershort, or £13 for the Boyleg Briefs (8 October 2026). UK delivery is free over £45, otherwise £4.50. |
|---|---|
| What you get | Knitted as a tube, so no side seams, in 79% viscose from bamboo, 15% nylon and 6% elastane, XS to 4XL (UK 6 to 22). The undershort has a 6 inch inseam. |
| Pros | No side seams anywhere on the body, and a 6 inch option that reaches where thighs touch. 4.5 out of 5 from 2,576 reviews for the undershort. |
| Cons | Sizes stop at UK 22. The Comfort Guarantee covers your first single pair of underwear only, and Boody does not take back opened underwear otherwise. |
Step One Women's Body Shorts
Best for: a bamboo viscose short with anti-chafe panels, if you catch its sale
| Price | £15 a pair, with 36 of its 40 colours at £9 in its sale (8 October 2026). Free UK delivery. |
|---|---|
| What you get | 95% bamboo viscose and 5% spandex, with Step One's Ultraglyde anti-chafe panels, XS to 4XL. |
| Pros | A lower price per pair in its sale. A 30 day first pair guarantee on your first single pair. |
| Cons | Step One does not publish the seam construction or a leg length for its women's shorts. Its size guide stops at 2XL. Its refund policy says sale items cannot be refunded. |
Runderwear Women's Running Long Boxer
Best for: running, with VPL and thigh rub to solve at once
| Price | £23 for the 8 inch long boxer, or £18 for the seamless running brief (8 October 2026). |
|---|---|
| What you get | An 8 inch long boxer in 92% recycled polyamide and 8% recycled elastane, 360 degree seamless, with silicone grippers around the leg hems, S to XL. |
| Pros | Seamless and long in the leg, so it helps with both problems. A 90 day chafe-free guarantee: Runderwear refunds you if a pair makes you chafe. 4.8 out of 5 from 197 reviews. |
| Cons | Fully synthetic. Outside that guarantee, Runderwear does not accept returns on underwear that has been tried on. Sizes stop at XL. |
Nothing at all
Some fitted clothing, particularly leggings and swimwear, is designed with a gusset to be worn without.
The trade: obvious, and personal.
Nude knickers, and what most brands get wrong
The oldest advice in fashion is wear nude under white, and it is right, but it is usually taught wrong.
Nude does not mean beige. It means as close as possible to your skin. Nude knickers that match your skin tone disappear under thin fabric because there is no contrast to cast a shadow. Underwear two shades lighter than your skin shows up as a pale block.
Most brands sell one nude and it suits one skin tone. If yours is not that one, a mid-brown, deep taupe or dark chocolate will do the job better than the beige on the packet.
The feel of freedom! No VPL! I must get another pair of the brown to wear under my white jeans. Highly recommend.
Rosemary, UK, verified review
And white under white does not work. White pants under white trousers are more visible than skin-tone ones, because white is brighter than skin and reflects light through the fabric.
Cotton and no VPL, the hardest combination
A lot of people want no VPL cotton knickers, and they are difficult to make.
Woven cotton does not bond, so a true laser-cut edge in 100% cotton is rare. Most seamless cotton underwear is a cotton blend with elastane, cut so the edges are raw or rolled rather than stitched.
Your realistic options:
- Cotton seamless knickers with a raw-cut or rolled edge. These work well, though the edge can curl after washing
- A cotton gusset with a synthetic body. Common, and it gives you the invisible finish where it shows and the natural fibre where it matters
- A longer leg in a soft natural fibre, which moves the edge somewhere it will not show rather than trying to make the edge invisible
Bamboo viscose, modal and Tencel sit between the two. Soft and breathable like cotton, and able to take a flat or seam-free finish more readily.
Is truly invisible underwear possible?
Under most clothing, yes. Under sheer fabric, no, and any brand promising otherwise is over-claiming.
Truly invisible underwear, or no VPL underwear as most brands label it, is really three things working together: no raised edge across your seat, an edge sitting somewhere the fabric is not pulled tight, and a colour close enough to your skin that it casts no shadow. Get all three right and nothing shows under normal clothes. Get only the first and you will still see something under white linen trousers.
What we make
Flissie women's bamboo boxer shorts: bamboo viscose, seamless at the back and sides with one flat seam at the front. A 6 or 9 inch leg, UK 8 to 30, one price for every size (£13.50 a pair, or £11.50 a pair in a 10 pack), dyed to OEKO-TEX Standard 100.
Best for: no line across the seat, when thighs rub as well, in UK 8 to 30
| Price | £13.50 a pair, the same price in every size. 6 for £75 (£12.50 a pair) or 10 for £115 (£11.50 a pair), with a free 30 day tub of our perimenopause supplement (worth £29) in every 10 pack. Free UK delivery on every order. |
|---|---|
| What you get | 95% bamboo viscose and 5% elastane, seamless at the back and sides with one flat seam at the front. A 6 inch leg in all 8 colours, including two nude shades, taupe white and chocolate brown, or a 9 inch leg in black and pine green. |
| Pros | No seam across the seat, where the line usually shows, and a hem that sits below the curve of the bottom. Buttery soft and breathable, and the leg stays put. Two nude shades suit more skin tones than a single beige. |
| Good to know | One flat seam at the front; under sheer fabric, a fully bonded brief sits flattest. The wide, flat waistband is made to stay put rather than dig in. |
| Reviews | 4.7 out of 5 from 336 reviews (Judge.me, 10 November 2026). |
| Guarantee | 60 days from purchase: full refund, worn or not (return postage is at your cost). Free size swap on your whole first order, as long as you try one pair and send the rest back unopened. |
Two things make them work as no VPL knickers. There is no seam across your seat, which is where the line almost always appears. And the hem sits well down the thigh, below where fabric pulls tight.
Soft and comfortable, especially like that they are smooth so dresses and skirts don't catch on them as you walk.

Which should you choose?
| Your situation | The best answer |
|---|---|
| White or very light trousers | Nude knickers in your skin tone, not white. Seam-free at the back, or a longer leg |
| Fitted dress, sheer fabric | Fully bonded seamless knickers, or a no VPL thong |
| Jeans and everyday trousers | Almost any pants without a raised seam across the seat |
| Leggings, mid-weight | Longer leg, seam-free at the back, such as Flissie women's bamboo boxer shorts (ours) |
| Leggings, very thin | Seamless brief, or nothing |
| Thighs rub as well as VPL | Longer leg. The only option here that also covers the thighs |
Not sure about the size?
Flissie women's bamboo boxer shorts run from S (UK 8 to 10) to 3XL (UK 28 to 30), all at the same price. If you are between sizes, size up, and if the size is wrong, we swap your whole first order free, as long as you try one pair and send the rest back unopened. Every order has free UK delivery and a 60 day guarantee: full refund, worn or not.
No VPL knickers: your questions
What does VPL mean?
VPL meaning is simply visible panty line: the outline of your knickers showing through your clothes, usually across the seat or the back of the thigh.
No VPL meaning: what does it stand for?
No VPL meaning is simply underwear designed not to leave a visible line, either by removing the seam, moving it somewhere fabric is not pulled tight, or bonding the edge flat.
How do I stop VPL?
Three things together: no raised seam across your seat, an edge that sits somewhere your clothing is not pulled tight, and knickers close to your skin tone rather than white or dark.
What are the best seamless knickers?
For bonded edges, sloggi's ZERO Feel Hipster (£13, or 3 for £30) and M&S's Body Invisibles (£14 for 3) both describe them; for a seamfree knit in viscose from bamboo, Boody's Boyleg Briefs (£13); and Runderwear's running briefs are 360 degree seamless (£18). If you also want a longer leg, so your thighs glide instead of rubbing, Boody's 6 inch undershort, Runderwear's 8 inch long boxer or Flissie women's bamboo boxer shorts (we make them) at 6 or 9 inches are the options. Step One do not publish their seam construction. Prices checked on 8 October 2026.
Does seamless underwear really work?
Under most clothing, yes. Under very thin or very light fabric, seamless knickers help but do not guarantee invisibility, because contrast and shadow matter as much as the seam.
Do thongs stop VPL?
A no VPL thong removes the line across the seat, which is the most common one. The waistband can still show under something very fitted and high-waisted.
What colour underwear is invisible under white?
Your own skin tone, as close as you can get it. Not white, which is brighter than skin and shows through more. Nude knickers only work if the nude actually matches you.
Can you get no VPL cotton knickers?
Sort of. Woven cotton does not bond, so true laser-cut edges in 100% cotton are rare. Most cotton seamless knickers are a blend with a raw or rolled edge, or a cotton gusset in a synthetic body.
Do boxer shorts show under clothes?
Less than a brief under most things, because the hem sits below the curve of the bottom rather than across it. Flissie women's bamboo boxer shorts (we make them) have no seam across the back at all, and a buttery soft 6 inch leg that stays put, in UK 8 to 30.
What are the best no VPL knickers for leggings?
Mid-weight leggings: a longer leg with no seam across the seat, or seamless knickers. No VPL pants with a bonded edge also work. Very thin leggings: a bonded seamless brief, or nothing, since many leggings are made with a gusset for exactly that.
What is the difference between seamless and no VPL underwear?
Seamless describes how the edge is made: bonded or laser-cut, with no stitching. No VPL describes the result, no visible line, and seamless is only one way to get there; moving the edge to where fabric is not pulled tight, as a thong or a longer leg does, and matching your skin tone are the others.
Is seamless underwear breathable?
Fully bonded seamless underwear is almost always synthetic, because bonding needs a fabric that will fuse, so it is usually less breathable, though Boody's seamfree knit is mostly viscose from bamboo. For breathable and smooth, Flissie women's bamboo boxer shorts (we make them) are buttery soft 95% bamboo viscose, seamless at the back and sides with one flat seam at the front.
How do I avoid VPL in a fitted dress?
Choose fully bonded seamless knickers or a no VPL thong, in a shade close to your skin, especially if the fabric is thin or sheer. A longer leg is a bigger garment and its wide waistband can show under something very fitted, so it is better kept for days when your thighs rub as well.
