Chacott Stretch Skin Sauna Pants The size tag has been cut off, so it's unknown, but I think it was either M or L. * I'm not sure if this is helpful, but I usually wear a size S leotard, but I always wear slightly larger pants. * They feel great and warm up quickly, which is nice, but I'm selling them because I wear other items more often. I've worn them a few times, and from my personal perspective, there's no noticeable damage. * The quality is in good condition, but I'm not a professional, so there may be some overlooked areas. Please refrain from purchasing if you are sensitive to such details.
