Wow, this bra is really beautiful! The wetlook fabric looks great in real life, although it really doesn't photograph well. The bra does run a little small in the cup, although not as small as the measurements make it seem (especially the cup depth) But since the bra is very open on top, it's actually not that small - it's just not a lot of bra overall. When measuring the gore, I only measured the actual gore not including the small buckle underneath.
I don't usually fit Cuvy Kate bras - my boobs are usually the wrong shape for the range: My boobs start at my collarbone, I think they are average on the top, firm and bottom heavy with lots of projection.
I decided to give this a try and size up from my typical size of 32H to a 34H in this style (a 32 band in CK is usually too tight even though I often fit a 32 Panache band). To my suprise the band is loose - I can do it up on the tightest hooks so I need a 32 back. Although there is a little wrinkling in the cups it isn't enough to size down in the cup. So I think my ideal size would be 32HH assuming the other bands and cup sizes are consistent.
Update: I tried the 32HH & the fit is much better in the band and cup. Some wrinkling in the cup but I think a 32H would be too small.
