I wear a 36DD in Victoria's Secret sizing, so I ordered my first Rosme bra in that size. The straps were too long and the band was too big even on the tightest hook. It constantly shifted during work and the girls were falling underneath the underwire if I lifted my arms. Not comfortable to say the least. My next order I went with a 34DDD thinking that would handle the problems, which it did, but then the cups were too small and caused that horrible boob "muffin top". I gave the first one to my sis and it fits her fine (she's normally a 38D). The second one is comfy, so I just adjust the girls from time to time. The next time I will order a 34G and see if that is my glass slipper-fingers crossed.
