These are lovely feeling pjs. The modal blend is very soft and lightweight, but they feel substantial and aren't see-through; they don't look or feel cheap. They wash and dry well (delicate, cold, tumble-dry low, in my case). I appreciate that the shorts are long enough to cover the booty cheeks sufficiently; these could be worn in front of overnight guests without worrying about exposing too much. They're pretty roomy; I'm busty, so the top fits about right, but the shorts are loose on the waist on me--not so much that they fall off, but I think the large would fit much better (unfortunately, I know the top would gape if I sized down). I am not crazy about the color...I'm blonde and pale, and my upper body is pretty much all the same color as the pajamas, so they wash me out pretty badly. My legs have a bit more color from swimming laps outside, and the color definitely looks better against that skin than against the rest of me. If I ordered these again, I'd definitely choose another color as this is more putty than the ecru/cream I expected (the color has grey undertones, IMO)
These are lovely overall, and they feel awesome. I wish they would eliminate the tags in the top, but otherwise they're very well-made. I don't sleep in pjs....I just use them for lounging... so I can't speak to sleeping in them but they seem like they'd be comfy in the summer.
For reference, I'm 5'10", 190 lbs, 38dd, 32 waist, inverted triangle/apple shape, wearing the XL. The top fits fine, but the bottoms definitely have some extra room. If you're not busty, a large would be a better choice; if you're bigger in the booty, these will accommodate.
