“I am 5'11, 160lbs. I am usually a small or medium in bottoms and I went with a medium. I am glad I did, the material clings to the skin a bit so it is nice to have a little extra room and it doesn't feel too tight on my body. My only issue is that I ordered the charcoal grey and no matter what seamless undergarments I tried the pants on with, you could see the lines very visibly. This is something that bothers me and I was hoping if I tried the black color I would not have such an issue. However, the company does not allow you to exchange for a different color so I have to return these pants. I'm very bummed.”
