I love this dress ! It's one of my favourites .
I wanted so badly for this dress to work out, but the way it fit was all wrong. I'm 36 c, 31 waist, and 5'7. I got a large, but the bust area is so off. It wasn't wide enough to cover my bra and the opening was awkward looking too. I think if the bust went down longer and the opening under the bust was smaller this would have been super cute.
This dress is gorgeous - good quality fabric, pockets, sturdy mostly. Unfortunately, the bust region is not intended for those with a large bust, in my opinion. I have tried the XL on with 4 of my bras and my bras all show through the cut out at the bottom so I will need to sew in lace/fabric to cover part of the hole or shop for a bra specifically for this dress (not sure a good one exists). Unless you are prepared to go braless, I am not sure I can recommend this dress if you are busty. Even if you do go braless, the straps are too skinny to support someone with enough bust to fill out the XL long-term. The straps don't cover even my skinniest bra straps while wearing a bra which looks a bit tacky (I will be wearing a cardigan I guess). I really wish this one had worked out because I love the fabric.
