I wear an XS and they are very big on me. I like them anyways though and roll over the shorts. I prefer only cotton pajamas and these are such a good deal. I bought my sister a pair for her birthday as well. 5'1, 95 lbs, size xs

These run both large and small lol, at least on me the top is huge and the shorts are quite skimpy. Maybe if you're short and bigger on top that would be better but the way the top is constructed with a huge neck opening and long straps it just seems like it would slip around and fall way too low on anyone unless they were sized way down and then idk how the shorts would fit. I like the cotton material though and it is cute but not really tailored for my shape

These are a great cotton pajama set, but they are pretty large. They have an elastic waist band but not a lot of stretch otherwise. I bought a small, but would buy xs if I got anymore.

This pajamas won't fit most women! Huge in the top and small shorts.
