This is "generously" sized, so I called it somewhat large, but you kind of can't go wrong.  I don't understand why, sometimes, I can't leave a review from my order summary page, but I did purchase this.  Weird.

It's definitely a granny-style gown, but it fit my criteria.  For some reason I had trouble finding the right combination of things.  For winter time, I want long sleeves, a longer gown to cover my butt when I'm curled up under the covers, and high up to my neck.  So, I don't care if I look like a granny as long as I'm cozy.  Material is nice; not heavy but adequate for a winter gown. It's not that "flannelly," but, again, adequate. I'm happy with it.
