To be precise, it’s not that your breasts get bigger, but that they look that way proportionally. Before upper-body liposuction, when I was skinny I was 75C, and before liposuction when I had gained weight I was 80D. After liposuction, since I went back to a slim body, I became 75D, and when I gained weight I went up to 80E or F..
I was originally someone who had a big complex about having large breasts, so this unexpected side effect(?) was a bit flustering, but I thought many people might not know, so I’m writing this.
