For the record, I'm 5'8 and about 120 pounds... I'm not round in any sense of the word... but I REALLY needed new bottoms for a beach trip. Grabbed these in a small, and man do they BARELY fit me. I had to keep them because I waited way too long to attempt to get them... but I would have sized up to a medium if I had had time.
