Royal Blue elegant maxi dress

This one's a stunner! Plunge neckline and criss cross straps in the back. I did have it altered; sewed in cups from a bathing suit so you can wear this without a bra worry free, also has a hook on the tail so you can lift it off of the floor for dancing. Size 6, my bra size is 36b and height 5"7 for reference. It's new without tags.
