This nightgown is cotton, big, and really comfortable.  I am short, so it actually hits me at my knees.  That's okay, because I like them longer like that, but it is longer then it shows on the model.  It is a nice, soft, thick cotton that provides warmth, but not too much warmth.  It isn't an ideal one for summer.  I love curling up on the couch, watching tv with a cup of coffee in the morning after waking up, with this nightgown on.  It appears to be high quality, and washes up well.  It runs large, so if you wear a small/medium, then go with the small.  The medium is pretty big on me, and I normally wear a small/medium.  So far, I really like it.
