Hey, ur boobs are still up near ur armpits because they haven’t fully dropped yet. Ur very early post op. Until ur 6/7 weeks post op ur implants are still falling down into the pockets made by ur surgeon.
Once they’re fully dropped and in place they will be able to fit into wired bra cups, they begin to fluff out and get more volume.
It’s too early to judge ur final outcome. I had mod + unders and mine are not under my armpit. I do have side boob however I had tht before I had my op also. I’m ten months post op today and the changes u go through are massive so don’t judge or fret them atm. Hope tht helps u!
