I was a small B, now a full C. I LOVED my small boobs before I had my kids, then they changed and I became less confident.
I let my PS decide what size, after I told him what I wanted. I am 5'10 and 155lbs. We went with 399 gel implants with a crease incision, using subfascial placement. Super easy recovery, just waiting for time to pass to get back into the gym. My doctor is really relaxed and confident, and spent alot of time answering all my questions.
