I rented this dress for my Batchlorette party. I am a 34C, it was a little tight up top, but felt comfortable for the occasion. It was also pretty tight around the hips. The fabric does not have much give. I ordered a size 4 and 6, ended up wearing the 6. If you are busty, you should size up. Loved the dress, it was perfect for my Batchlorette party.
