I had breast surgery in Busan. It's been about 8 months since I had it. I had it slightly larger with Motiva. I had it about 400, so it's 34 inches. I think 70D or 75C would fit for underwear . To be honest, I regret having it too large... but I'm satisfied because the texture is so good. I made a reservation because I really wanted to do it, but when the day of the surgery came and I arrived at the hospital, I was so scared that I was about to run away, but the doctor was so kind and reassuring when he designed it for me, so I didn't tremble and had the surgery. I think the surgery went really well. I had it slightly larger, but the texture is so soft that a friend of mine said that when he touched my breasts by mistake, they felt like my own flesh and he didn't even know they were breasts.
