Brand new, can't return!

Brand new dress, can't return it. It's a size too big for me. Beautiful dress with a corseted top. Falls so well on the body. I love a dress that you don't have to worry about sucking in all night. Size medium and fits like a true medium. Stunning for a spring or summer wedding. I'm 5'9 and it shows my feet in the front, but touches the floor on the sides!
