Wow, I can't believe how tight this band is, I would have to wear a 34 in this style. So go up one band size from your usual. The cup is one size too large for me. So ideally, I would try this in a 34C, which they do have now, but they don't do exchanges. This would fit a 30F US most likely. The cup fabric is slightly stretchy so the depth actually stretches to about 9.3" or so, the measurements in the data table are non-stretched depth.
This bra is OK. The underwire ribbing in the sides (under the arms) tends to dig in along the bottom of the band, making it uncomfortable after awhile. The top of the underwire under the arms also tends to rub. Boobs also tend to slide toward the center where there is no fabric, causing slight quadboobage. Straps are comfortable though.
