I am between sizes so I sized up and it was too big. However, that extra space came in handy as you have to unzip the dress the use the bathroom, so it was easier to zip/unzip by myself. Also, mobility is extremely limited at the knee (seam at feathers does not stretch - you cannot pull it up) and I left feathers everywhere - they were just falling off the thing. However - so many compliments and I looked fantastic.

Fits great & looked very nice. The only problem is that the feathers keep falling out leaving a trail. I lost a lot of feathers from the dress.
