Two people, doing underwear differently.
2021, DerbyshireWe’re Phillippa and Matthew.
We started Flissie in 2021 and we still run it ourselves, from Derbyshire. Two people doing things our own way, and reading every review that comes in.
The ideaComfort should never be traded for style.
Most knickers ask you to choose. Lace that digs in, briefs that ride up, cotton that clings when it’s warm. We wanted underwear you could forget you had on: soft against your skin, cool on a hot day and still in place at the end of it.
The designSo we made the boxer that stays put.
Choose your lengthBamboo viscose that’s soft from the first wear. A wide waistband that doesn’t dig. A leg long enough to stop thighs rubbing, in 6 inch or 9 inch, with leg bands set so they don’t roll into a rope. UK 8 to 30, and every size is the same price.
YouThen we listened.
Read the reviewsWhen we went through all 336 of our reviews in October 2026, 76% mentioned comfort and 40% mentioned softness. We’ve written up what women actually told us about their underwear, the good and the less good.
Our promise60 days to decide.
How the guarantee worksWear them, wash them, and if they’re not right, we’ll refund you. Your first size swap is free too, so you can try one pair before you open the rest.
2024Then, a supplement for perimenopause.
Meet the supplementIn 2024 we launched our first supplement, made for women going through perimenopause, with every dose published on the label.
