Snap single strap navy blue cocktail dress - barely worn

This is a size medium cocktail dress in a deep navy color with a slight sheen to it, as well as a single strap that is embellished with flowers both along the front of the strap and asymmetrically along the front of the dress on the right side (as shown in the picture). It is a bodycon dress that is stretchier than it looks, and has a zipper in the back. It was worn twice by me, once to a high school dance and once to a wedding.
