5' 4" 115 Lb Breast Augmentation - Draper, UT

Hi Real Self world! :)
I am wanting a very natural result, and it's so nerve wracking to figure out what will get me there! I would love to be able to "dress them up" with nice cleavage in a bikini or "dress them down" in a cute oversized sweater, and still look thin-framed, if that makes sense.
I'm 5ft 4, 115 lbs, and I currently fill a 34a cup decently with slight drooping from 3 kids. I'm hoping to be a smallish c cup afterwards, but definitely NOT a D cup.
I went to my consultation with Dr. Self, and he was so nice and made me feel very comfortable. Based off of my goals, he felt I would be able to achieve a very nice result with a Natrelle inspira moderate profile silicone implant under the muscle for the more natural result I desired.
When trying on the sizes...it really was strange. First, the nurse had me try on the 325 cc (exact cc's I actually can't remember) I felt pretty ridiculously huge to be honest, but all my friends warned me to not really take the sizers too much to heart since it will always be smaller under the muscle. I think the size I felt most comfortable was a 265 cc (but I probably should have tried a size smaller just to see if I liked that too because I feel that even those might have been a tad too big).
After booking the surgery, and as my surgery date is getting closer and closer...I've been doing a TON of research, and have found out a few details that I probably want to consider, and some questions I didn't know to ask with my previous consult.
First, my doctor did measure my BWD (and a bunch of other dimensions) but I don't recall him telling me what my BWD is. My measurement from my clavicle to nipple was about 12cm on both sides though via my PS.
From my own measuring, my BWD is around 12-13 cm.
So considering this, I've been needing to ask my PS to assure me that the implant we end up using will match my BWD well so I don't end up with a too narrow or too wide result. Based off of my research, I feel a smaller and moderate profile will match my BWD nicely though, just like we discussed, so that is comforting.
Getting super nervous!!!! Hoping that I will love the end result. Really wanting to look good in both clothes AND a bikini :).

Before BA. Slight drooping from breastfeeding 3 kids.

I've spent so many late nights here on Real Self, and I'm getting SO nervous!! So many "what if's"are popping into my head it's really beginning to stress me out.

Biggest concern is going too big. I honestly feel that I won't get the "boob greed" that everyone talks about, because I like having a bit smaller boobs for the clothes I wear...I'm not bothered by my boobs in clothes, I would just like an extra "umph" for bikini's or naked. Those I am definitely self-conscious in.

My husband is adamant that I go bigger, so I don't regret it, but I really would hate it if I went too big. I don't want to feel too heavy or matronly in clothes. I've scaled down my wish boobs, because I still want a petite look. I'm now even considering 250 ccs or less...
Anyone else in the same boat? It's harder to find before and afters in smaller ccs
