I bought this nightgown for my daughter.  It arrived a week before she was due and I asked her to try it on so that if it didn't fit I could send it back and get the right size.  Not only did it fit, it  even stretched to accommodate a very large baby bump.  She found it so comfortable that she has worn it everywhere as a dress. Baby will be born tomorrow and I suspect that shell be getting a couple of more because she loves the one she has!
