I got the medium size and it's a little loose. These are great for me. I am 5'7" and  133 lb. I should say I am a guy. I was worried they won't fit because I thought womens cloths were so different from men's but there is no difference; it's just a stupid cultural myth that dumb people have made up. These fit me better than any "mens" shorts(which are always too long for biking). That might be because most american men are fat-assess so the manufactures have changed their standards for "MEDIUM" size. These are great for any athlete, man or woman.

Overall a worthwhile purchase. *****
