I got this as a "hot buy" (or whatever they call it) & sadly, the sizes weren't properly listed so what I thought was a 3x wasn't & can't be used as a gift for the friend I had in mind. However, I decided to keep them (I'd gotten 2 sets) for myself & O my; they are SO soft, light & comfortable. The inside is lined with brushed fleece & they aren't unbearably warm as some pajamas can be. I am almost glad of the sizing mistake as I am a fan of pajamas & the price was fantastic.
