I've been looking to replace my GAP Breathe high-rise briefs for YEARS now, since they're no longer made. NEGATIVE is the first and only cotton underwear I've purchased that lays on the body, without tightening up around the waist or the thighs. I bought the briefs first, which were a little low for me, but then bought the boyshorts. WOW WOW. Now I need to buy 10x more. I am a fuller-figured woman, 155 lbs, size 29 pants and a small waist. I bought the M/L and they fit great. I'd also be interested to see how the next size up fits. With larger hips, tummy and booty, these underwear are perfect. PERFECT.
