I am 5'8, 150 lbs, do you think 575cc implants will be to big for me? (photos)

I am 5'8, 150 pounds, curvy through hips/butt. I had a full anchor lift last year and now I'm going in for stage two of having implants, my dr wanted to do it in two stages because of the degree of my sagging. I have chosen 575cc mentor mod plus silicone under the muscle and now I'm starting to panic that it will be to big.. I just want to balance my body.
