Glenda, this designer has really unique dresses, maybe browse through her site, if you go to her site and look at runway it shows you both front and back of the dresses. I couldn't pull this off because I have a booty, Amy (AmyHMartin) told me in high school, "you can tell you are a little latina with that butt" not sure if that was exactly it, but that was certainly the jist.
But Glenda, you have a year to figure it out and I am sure you will find something, or you could take the parts of this dress that you like and have it created for you? Just a thought
