As others have said, the size of this model is oversized. I usually wear 2XL or 3XL if I want something loose. I ordered a 4XL based on other reviews and it fits like the smaller 2XL. I have sleep shorts in the same fabric and they fit as expected for their size so this product confuses me. The fabric is very thin and almost transparent. You won't be wearing them outside, but they're very comfortable for lounging and sleeping in, and are surprisingly breathable for such a soft polyester.
