I had the surgery in Busan. I originally had no fat on my upper body. When I went to various UNICEFRA hospitals, the teachers said that it was a difficult case to perform surgery on, and that the chest circumference was small and the skin was too thin, so it could easily show through... I had 1CC implants in my heart when I was young. I did it because they said they would put a bigger one in, but I regret it now. You have to put in a size of silicone that fits your breasts so it doesn't look unnatural. I tend to show off a little, so make your decision carefully.
