I purchased these in a medium and they fit like an XL. Seem comfortable, but is basically a nightgown and shorts. Hope this helps.

I bought as a gift. My granddaughter loves them. No tight fit. Lives in Las Vegas so it's pretty warm for many months. Cute. Her name is Katie so Kittie Katie has Kute pj's.

Very comfortable and cute. A little big, but that's ok.

The tops run small but they are very soft
