I was the same but once I got it done I realised there is not much difference in 40cc, I had 345 in one breast and 385 in the other to correct a small size difference, I would go for the bigger one for sure. They look a lot bigger in your bra in my opinion, once inside you they look completely different. One of the biggest complaints on here is that boobs don’t look big enough post op. 40cc really isn’t a lot so don’t worry and go for the 410
