39 Yr Old Mom of 1. 5'9 138 Lbs. Natrelle Gel unders. Love them! Sarasota, FL

Hello ladies. I am a mom of a 21 month-old little girl and I'm about to turn 40 in a few months. I decided I wanted new boobs in 2015 as new year-new me resolution. Also being that I don't plan on having more kids, I feel like this is a good time. Also talked to my husband about it, and he was very supportive, Yaay! I had small boobs all my life but being that I've had a svelte figure all my life, I was always comfortable with my small boobies because they were perky enough to not even need a bra sometimes and I felt they fit my body. I went from size A to 34B when I was pregnant, I then decided to exclusively breastfeed my baby, which left my boobs deflated after I breastfed her for 14 months. During the days that I was weaning her off, I was going through the swelling and painful withdrawal discomfort but my boobs got gigantic (I guess from all the milk filling up). I attached pictures. They were very painful but I LOVED their size and wished they would stay that size. Well a few days later, I couldn't believe how deflated and small they got. It left me depressed about my body and not feeling sexy. I then started wearing more padded bras and even sometimes doubling bras just to fill my tops better. Anyway, I readily found this site through Google and since then, I have mainly just been reading a lot of member's stories; all very inspirational and educational. I did find a reputable plastic surgeon in Sarasota, FL (1hr and half from my house): Dr Scott. 2 weeks later, I went to my 1st appt with Dr. Scott, who had a amazing staff, and he himself was really good at talking to me and addressing all my questions. I felt comfortable right away with him, so I decided to book my procedure that same day, for April 16th. I still do need to go back on March 26 for my pre surgery appt, to get more questions addressed, try some sizes and decide how big I want to go. I am thinking about going at least 400CC, or maybe 470CC high-profile. I don't want them to be ridiculously big but I don't want to go through the surgery and coming out with a size that I won't be satisfied with. I guess a case of boob-greed haha
I hope 470CC won't look too fake on my frame but I want to go as big as I can get away with. I am 5'9, 140lbs. What do you guys think? Would that look too "fake" and big? I appreciate any ideas and suggestions. Thank you for taking the time to read my story.

Boobs before the big deflation. I would actually be happy if I get back to this size with the implants.
