Runs Small

I normally wear a size XL and ordered this in XXL. I have never had a problem with sexy nightgowns fitting when ordered from Amazon, but I could not get this over my shoulders. There doesn't seem to be much stretch. Another negative is the panties that come with this set are not lined at all. It's the same unbreathable satin material all the way through the thong, and I'm not comfortable wear something like that for too long. I was really hoping to have something sexy to wear at night for my husband but am sad to say I couldn't try this on.
