Knickers that actually fit your body!

CYA (aka Cover Your A**) your new go-to knickers.

Tired of those ill fitting undies too?

Most underwear brands offer very limited sizing e.g. S, M, L, etc. that assumes a standard 10 inch difference between your waist and hip measurements. In reality this can range from 2 -15 inches or more.

When each bum is so unique, why shouldn’t the sizing be?

Meet CYA: Knickers tailored to you, down to an inch.

Bringing bra sizing to underwear.

Rather than just a Small, Medium or Large, at CYA we borrowed the tried-and-true bra sizing system and brought it to underpants by using your waist and hip measurements to giving you perfectly fitted knickers

You will now know if your bottom is a 32B, a 33F, or a 35C and be able to find your perfect size out of 50 sizes currently available.

Are you ready to give your bum the space it deserves?

Say CYA to excess fabric, too tight a waist, or that uncomfortable wedgie following you around all day.

At CYA, we believe that your bottom deserves as much attention and care as your top and we’re here to give your bum the space it deserves!
