    Perfect fit!

    I have nothing but good to say about this brief. It would be great if they provided more coverage on the underside. However, my autonomy is a little different than the average customer. I have tried hundreds of briefs, bikinis, boyshouts, etc, and these are the are the hands down winner. The cotton sting bikini are perfect for my spouse and the sieve bra is unbelievable perfect. In my opinion Nrgative is without competition! Thank you for the innovative and wonderful products!

    Love it

    I love these briefs. Most briefs either come up too high or give wedgies. I love the fit of them. I have a very high waist that is very small and giant butt with wide hips. These are the perfect undies for me. Make them in every colour, please. I will buy them
