Polka dot retro/vintage dress

Black and White polka dot dress. It buttons up from top to bottom, with one snap at the bust to ensure there isn't any gapping. It is hard to tell in the pictures, but there is a second layer of material attached to the dress that ties under the bust. Very rockabilly and sexy. I've gained weight and my chest is too big for the dress now (36DD). The length is a couple fingers width above my knees. I purchased it at Francesca's.
