21yrs, No Kids 5'3" 113lbs 450cc High Profile Silicone

So I'll start off with my stats, I am current 20 years old and will be 21 by my surgery date which is May 15, 2015. I've wanted large breats for as long as I can remember, I knew I was never going to naturally have them so I knew I would eventually have to get implants. Well after many years I finally decided to book a consultation with Dr Mark Haugrud in Calgary, AB. I was recommended by my boyfriends mom (who previously had her implants placed by him) and she said he was amazing and she loved her results.

I have my first consultation March 4th, 2015 and Dr Haugrud started by telling me how the procedure works and the risks, etc before I even asked. It made me feel confident that he was a really great doctor and obviously knows what he is doing. I currently measure as a 32B and my BED is 12.5cm and am looking to get to a 32DD or possibly even a 32DDD. Dr Haugrud have me the 450cc high profile implant to try on, I tried on the 500cc and the 550cc and decided that I liked the 500cc but since my BWD is so tiny he informed me of having side boob, also told me he could fit the implant but would rather me have the 450cc. So now I'm stuck between choosing either the 450cc high profile and 500cc high profile silicone. I have another appointment on April 16th just to confirm the size that I want and I will bring my boyfriend with me so that I can get a second opinion. I don't want to look like balloons are on my chest, I want large but not too large. Any ladies out there with similar stats and photos of 450cc hp silicone or 500cc hp silicone? I need help!!

So I just went for my last appointment before my surgery. Dr Haugud answered all the questions I had written up, very helpful and intelligent guy. I got my doctors note, made my payment of $9015!!! And booked my post op appointment. I can't believe it's really happening!! 29 more days until my surgery! I decided on the 450cc HP as the doctor STRONGLY recommended it for my small frame. Now it's just a waiting game. I didn't take many photos, but here's what it looks like with the 450cc sizers.

Here are some photos of my breast size currently before I have my BA. I measure as a 32B but can oddly fit the 32C depending on the bra!

I'm very excited for my BA journey as the days can't come sooner!
