I am 5\'10 and 150lbs with long torso so I was unsure with the sizing. I purchased the medium based on measurements and had to return because it was too small. The large fits perfectly! I love this product and I love the way I feel in it. Downside is even with the crotchless feature, I still had to undress to use the restroom (doesn\'t seem sanitary to me not to, but that\'s my preference).

I just tried it on last night 10/06/16 and I ordered a 2x it fit perfectly. I can bend over and still breathe. After 20min of wearing it, it gelt like i wasnt wearing it. It sucked in all my important areas. Plus looked good under my clothes. Wearing it daily and all day at work in the operating room under my scrubs.

Perfect to slip under any tight fitting outfit
