First perfectly ! I was worried about lack of support (currently grew to a 34 DDD from 34D - thanks to my 6 month old baby lol) I’m usually a small in dressed so I was worried I would have to size up for the bust area to fit well but it fits great with the small! I feel my original 34D size (or even smaller) would work well in this dress just the same because of how the bust area is design with a bit of stretch.the material is a light sequence, not itchy and accentuates your curves! Def a great buy!
