My back is a 34. My bust is DD, and I have a nice size butt. And this fits perfect!! The reviews had me ready to purchase a medium, but I went with my instincts and got a small. I am very happy I did. This dress is sexy. The material is beautiful! And this dress fits like a glove smooths your body out! Snatched! I'm gonna wear this for my birthday in October. so I have no pics now! You should definitely get this. Just keep in mind that everyone's shapes are different, so you can't go off what everyone says!
