The flannel itself is decent quality and the pajamas are properly made. However, the fabric is thin, so these are not super wooly ultra cold weather pajamas. This is good for our purposes.

I bought a medium (which purports to fit someone up to 5 foot 9) for my fiancee, who is 5 foot 4. After washing they shrunk so much that I ultimately had to cut off the feet to make them usable. A medium would probably comfortably fit someone who is 5 foot 1 or less. So, that being said, had I known what I know now, I would have bought a large for a five foot 4 woman.

The supplier doesn't quite know what is going on with their product, which is obnoxious.
