28yo. 5'4" 130lb, No Kids, 575cc Mod+ under muscle, Mentor Smooth Round Silicone

This is what the look like now, officially 5 months post op!
They feel pretty much like a natural part of me. I don't feel the implant when I massage any more, when I'm switching positions while laying down, there's almost no remider of me having big silicone bags in my chest (your body has to get used to that!!)
I'm experiencing shoulder pain and have to learn how to have a correct posture with these big breasts now, and I have to strengthening back and shoulder muscels at the gym.
I absolutely enjoy them and believe I have received even more than I hoped for.

I've put together (with the help of my RS friend @aolson6370) a real life example of comparable silicon implants with 2 different profiles: extra high profile and moderate plus profile.
This is a very important decision you and your PS should come to as you prepare for your surgery since profiles can affect the shape of your breast and the overall look of your body.
Top photos are @aolson6370 who has 580cc extra high profile silicone implants.
Bottom photos are me, at 575cc moderate plus profile silicone implants.
@aolson6370 and I share VERY similar body stats and 5ccs of difference in our implants don't make any visible difference.
We are also at a similar stage in our recovery, I believe I got my surgery a couple weeks before her. We're both now at around 4 month mark.
I hope these visual comparisons help you decide and communicate to your surgeon the look you'd like to achieve.
There us also of course High Profile, which would be somewhere between these two pictured implants.
If you read thru my review I'm very specific in the type of result I wanted to achieve: I love the full, natural looking breasts. Kinda like soft, pillow, wide boobs. I'm all about having a lot of side boob and underboob (under nipple tissue), while I am NOT a fan of the upper pole fullness or projection. I wouldn't feel comfortable with that. Everybody has their own vision of how they wanna look and what they feel comfortable with, and there's nothing wrong with that.
My friend who is featured as the top photo in the collage, likes the projection and you can read more about her preferences on her profile (search her username on RealSelf for a great detailed review)
This post is purely educational and it does not promote one shape or person's results over another. I believe @aolson6370 results are beautiful and I'm truly happy for her!
Scroll thru the photos to get more details as we examine these different boob shapes together :)

Ladies Nordstrom Rack is having a 25% off sale on CLEARANCE items. They carry so many great bra brands: Freya, Panache, Fantasie, Glamorise, Chantelle, Natori.... And they have BIG sizes!
Small bands, large bands and BIG cups, which is what most of us need.
I just got Natori Yogi sports bra at Nordstrom Rack, which costs $70 (tax included) : https://www.amazon.com/Natori-Womens-Power-Contour-Convertible/dp/B071KNTG8V/ref=sr_1_1?ie=UTF8&qid=1522454951&sr=8-1&keywords=natori%2Byogi%2Bsports%2Bbra&th=1&psc=1
Except I paid $22 for it at my local Nordstrom Rack today. I can get 3 of them for the price of one (unfortunately they only had 1 left :( )
So go today! You will most likely find a high quality bra or a sports bra for much less than anywhere else.
If you don;t have this store near you, the sale is on their website too but their website selection i in lingerie is very limited. They have so much more in stores.
I'm not absolutely certain if their Return policy covers Clearance too, but it probably does since I wasn't told otherwise.
