I bought a small, even though I’ve never worn a small in shorts. I have an athletic, muscle, and conditioned build due to being a natural pro physique competitor. I’m a legitimate 30 waist line in almost all my shorts, pants, etc. However I’m 5’11” 190-200lb and the small worked out perfectly based on on the 30 inch waist line chart. I simply followed the other reviews and sizing chart. It fits "my” glutes perfectly, not too short (for me) and not too long. I wanted these to swap between wearing no 3/4 inch leggings for men and sometimes wearing them. They were comfortable. NO compression just form fitting to accentuate the thighs and glutes. I simply don’t like baggie clothes since I’ve trained hard to earn the physique I have . I’M BUYING A COUPLE MORE.
