Sequin dress with gorgeous upper back cut out.

Bought this dress for $190 and wore it a few times but have gained weight since. I've included photos of the same dress in purple with tags to show that this is the retail price of the dress, but the one I'm selling is the teal one, not purple! Excellent condition with no noticeable flaws. It has a nude lining and a round cut out that shows off the upper back. XS but it stretches pretty well. It fit me up until I started wearing a size 8.
