“I was nervous to order these because the size chart made it look like they would not fit me. I usually wear a US Women's 18/20, and I have a 41-inch waist. The size chart for the XXL (the largest size) showed that it would fit a 38.5-inch waist (which is small for a typical size 20). Well, these fit me perfectly. Whew! I'm not even relying on the stretch fabric; so, if you are usually an 18/20, I'd take a chance on them. The fabric is super cozy as well.”
