I love these shorts and so does everyone else that buys them. I sold out 6 times last summer and I've brought them back. I have 5 pair of them and I wear them under dresses that are a little short...(just in case) and I also wear them to sleep in. Yes, I love sleeping in them. Not only are they great to throw on with a t-shirt when lounging around the house but you can sleep in them with comfort. I'm a size 5 pants and I wear a small. THESE FIT TTS. You can size up 1 size if you like them loose for lounging or sleeping.
