I am 5'11", 160lbs, average build. A large fits me perfectly. I usually hate swim suit bottoms because as a taller person, it always felt like my hind end was hanging out. I do not feel that way with these! Full-coverage bottoms that are still attractive. The rise is mid-rise but you could maybe fold the top down to make them low rise. Personally I like the rise as it helps hold in some tummy bulge without seeming too "mom-ish." Great buy!
