I always order a 2X in nightshirts (I wear a L to XL normally) because I like my nightshirts to fit comfortably/loosely. This one is too snug, which means that -- as has been the case of late -- the company selling these don't comprehend US women's sizing. My husband went to the store and purchased me a replacement 2X nightshirt which I literally swim in because it's so big. Maybe I'll put this aside for when I become really stick thin and then perhaps I'll be able to wear it as a night shirt. If it weren't for the length and the giant print on the front, I could wear it as a t-shirt.
