Simply marvellous

These ladies boxer shorts are simply marvellous under my scrubs, no more creeping underwear. They're definitely moisture wicking, very lightweight, and really, really comfy! Would like a few more colours to choose from please 😀


Very comfy! Not as high waisted on me because I have such a large bottom lol

Flissie? More like fashion!

When I found this page I was immediately in love and ordered it within minutes. This is what fashion industry should be about! Pretty, comfy, good material and biggest bonus it’s for a good cause! I bought three pairs because I love what I’m reading. It came pretty fast. When I opened it I was soo excited to try them on! The Sage and Fawn color are just a little bit see through but no biggie it’s an underwear after all. Plum came with 3 really small stained dots unfortunately I was not able to wash them but I don’t really mind that much. Otherwise everything was perfect, I definitely recommend it. Everyone needs to have their own pair of Flissie! :)
