250cc or 280cc moderate? (Photo)

Thanks for your question! When the implants are in your body and under the muscle, they will look a little bit smaller. I always advise patients that if they are torn between two sizes, go with the larger. Good luck!

I can understand your concern. The main reason to consider different size implants is to correct asymmetry between the two sides. I would imagine your surgeon has noted that and is trying to correct it.
The best option would be to try a 250cc on one side and 280cc sizer on the other and see how you feel about how that looks!
