This hoodie-footie is well-made and uses a nice, plush material.  I ordered the animal print, because another hoodie footie I'd gotten in black instantly showed every bit of dust and pet hair.  Not a problem with the animal print.  Also, the material of the other garment (Jumpin Jammerz) itched like crazy.
As for sizing, the small fit me to a tee. I'm 5'5-1/2, 118 lbs. size six and a size 6.5 shoe. I wear socks and very lightweight pajamas underneath the hoodie footie, and it's still roomy enough.  The feet have nice felt tread dots on the soles, so you don't have to worry about needing slippers.  I wear this to bed and around the house. Keeps me warm.  If I need to run out to get the mail, I can don some boots and not look too fruity to people if seen.
Very glad this product was no longer out of stock.
