I usually wear small-medium size underwear, so I got medium just in case. I really like briefs, so I was excited about these. Maybe it's just because I have a larger booty, but these were not briefs. They have almost 0 booty coverage. It makes me really sad because they fit my hips fine. They do look great under leggings except for the bow in the front. I just cut it off.  Oh well. You get what you pay for.
