J. Crew Black and White Polka Dot Dress with Pockets sz 6

Super cute strapless dress from J. Crew in size 6. 100% cotton with a cotton lining. The tags have been removed, but it has never been worn. There are white straps inside the dress (I honestly don't know what they are for...maybe more support??) but one of the hooks has come off as shown in the photos. Not noticeable when worn!
