High quality, great feel, sized big for tucking

High quality, great feel, sized big for tucking. You may want a smaller size if using for a holding layer for tucking. Feels great though for longer time as a to layer.

Really comfortable would recommend and will be buying again

Actually comfortable!

Compared to gaffs that are heavily advertised for their ability to tuck in order to boost sex appeal, this underwear is functional first and foremost. I can benefit from wearing these at work for an entire shift without irritation or chafing, whilst also enjoying a compression that is less extreme, but just as affirming. I'm definitely getting some more!

Top quality clothing

I’d recently bought the briefs and loved them so much I bought a 2nd pair in black. I also treated myself to the animal print swimming costume. Historically I had been put off by the prices but it’s true you get what you pay for certainly in this case. Highly recommend
