Spaghetti Strap Dress with Back Hallow Pretty Blue

This is such a cute and soft dress for the summer. Can be dressy, casual or the perfect in between! It has never been worn and I have no information on it, other than I bought it at a small, high end boutique on the beach (I live in Florida) , it is a size medium to large. It is a very pretty shade of blue, and has 2 layers, like a built in slip. It's lived a very boring existence in my closet, I forgot all about it because I don't wear dresses...Sooo I'm hoping to find it a fun new owner soon.
