Keeping breast shape

So i have a very large chest (E size cup before pregnancy) and I have been pumping since my baby doesn’t latch. I wanted to know what I could do to maintain my breast shape and lift as much as possible since a very saggy large chest is just going to create back problems for me. I’m wearing a pretty supportive bra at all hours but wasn’t sure if there is anything else I can do. Thanks!
