THE BRIEF- ONYX

The Brief is where it all began, tucking underwear reimagined.


Designed with comfort as the primary focus, the Brief provides a super-flat tuck and can be worn all day long, without fear of pinching or the uncomfortable tension that comes with wearing underwear that isn’t designed with our specific needs in mind.

The Brief is comprised of a four way stretch power-mesh layered beneath durable lycra. These two fabrics combine to keep you securely tucked whilst delivering the results you’d expect from shape-wear.

The Brief is cut high on the leg producing a feminising effect with an elasticated leg cuff to keep everything where it should be, this makes it ideal for wearing under
formfitting clothes.

The waist band of The Brief is lined with silicone dots meaning that, however you move, your underwear is going to stay in place.

Our underwear has been specifically designed to fit you without needing to size down, please order your correct size, if you fall between sizes, select the lower size.

PLEASE USE THE SIZE GUIDE TO ENSURE YOU ORDER THE CORRECT WAIST MEASUREMENT, WE ARE UNABLE TO ACCEPT RETURNS FOR WORN UNDERWEAR.

I ❤️ love these!

These are fantastic, I highly recommend them. They transform a small bulge to a smooth curved mound. I would recommend buying as small size as you can get away with. Goes great with leggings, trousers, tight skirts and dresses for a wonderful feminine look!

Works wonderfully

Could be *slightly* tighter (I ordered the smallest size and it’s not a massively tight tuck), but there’s a balance between appearance and comfort and at the end of the day these are some of the most comfortable knickers I’ve ever worn. Definitely will be picking up more of these

Why are all the bottoms so high waisted ?

I wish u had a swim bottoms that are normal bikini cut, that high waisted look makes me think of “ mom jeans “ or just how old people pull their pants up so high. Personally I would never wear a thong , and those are the only options? Hopefully u take this into consideration and put another option up soon. Love u.
