Family Matching Christmas Santa Claus Pajamas 2 Piece Set Sleepwear for Women Mum Size L

"100% cotton"... Hmmm, it may have cotton in it, but there's also a stretchy, spandex style fiber in it that allows for easy movement, and dosen't have any negative aspects, but they don't have a flannel feel.They do run small, I'm a guy, 5'10" 230# and the XXL is a minimum. Go a size up from what you're used to.

My daughter-in-law wears a medium but I ordered her a large just to make sure it would fit well. She ran it thru cold water then put in the dryer and it shrunk up two sizes. Fits really tight. I can't believe it shrunk that much. I think it is sized small. The baby needed a size 3 and that was what I ordered...hers was also ran thru cold water and put in dryer and it did not have the shrinkage problem the adult size had. Sorry I ordered this...
