The band on this bra runs about a size tight- I tried the 32DD but the band felt as snug as some 30 bands, so I would definitely size up in the band. I felt for me that the cups ran small, as I has quadboob in the 32DD which is usually acceptable as my first bigger band sister size. They didn't have one, but I would have tried the 34DD to check for cup volume and see if the band was passably snug.
This bra seems to run small in the band, but true in the cup. This in a 30D was too tight around the waist, but if I unhooked the band the cups would have fit. I think this in a 32C would probably fit perfectly. This bra has wide set straps with gold accents (I though it had black accents, so I was surprised when it came). This band is not very stretchy and is a fused neoprene feeling fabric. I think this band might be hot.
The cups have a textured mesh overlay that is not fused to the lining. I looks modern. Straps adjust half way.
