Hiiii ☺️ I had my op 1 week ago! I have similar stats to you, I’m 5.4, 8 stone. I had 325cc HP unders. I previously wore a 32C but was probs a B/C and currently in a 34D. I was worried mine were going to be too small but they’re looking like a good size at the moment, although only 1 week PO so going to change a lot xxxx
