I purchased this item because the description stated it had a cotton crotch.  However, it is the *lining* that is cotton; outside is the same fabric as the rest of the item (nylon).  I wanted something that would breathe; this will be no better than any other of the shapewear out there.  Also, it has an extra layer of fabric for the "panty" which suggests to me that it will be hotter (and thus stickier/ sweatier) than other shapewear.
Very disappointing.
