I am a 40DD, and have a hard time finding bras that fit just right.  I ordered this bra while I was looking for lacy bras with an underwire.
The cups on this bra have a liner, and a lacy outside.  I'm not sure if it was a manufacturing defect or just the way the bra was designed, but the liner layer was a size smaller than the lace on the outside - this meant after trying the bra on, there was a significant amount of extra lace fabric that was folding over itself.
