This costume is gorgeous and comes with a choker and tiny top hat with a red bow and tule. I am a size 20/22 and a size DD to DDD, I bought in a 3x/4x. This dress was hard to get on over my chest both feet first and head first, mostly because the waist does not have any stretch and is tapered. And as far as the cup size goes... my chest is spilling out of them. The cups themselves are shaped weird, you can even kind tell on the model, in the center of the cup it is tighter and sections off the bust.  Kind of disappointing but I am going to make it work, I may have to wear a shirt under it. I got this costume to make into a queen of hearts costume, I liked it better than those costumes. I got a black petticoat to go under it, it looks really cute because the ruffles stick out of the bottom, its pretty short too. Overall, nice costume, beware if you have a large chest.
