I'm about your age and I had breast implants last summer. If you can afford it, I say go for it. It's really worth it.
I was a 32A (in VS Pink) before and afterwards I was a 34C (in VS Pink) bras. My boobs have grown by themselves afterwards though to a 34D in Target bras lol. I was worried about going too big, but I actually wish I went bigger. Fake boobs look smaller than natural boobs of the same size for some weird reason. You also get used to them pretty fast. Sometimes I'll think "Dayuum, I wish my boobs were bigger." but then I remember what I used to be. One thing I didn't know before the surgery was that since your boobs will be a lot perkier than normal boobs, you have to watch out for nip slips. seriously, all VS bikini tops give me a constant nip slip haha. Also: WAX YOUR ARMPITS BEFORE SURGERY. I didn't and dude, it was the worst mistake ever.
Messege me if you wanna know anything else!
