In my opinion you would more than likely require a lift to restore a perkier shape Implants alone would leave you with breast tissue dropping of the front of the implant It can be done in 1 stage or 2 , uplift first then implant or combination. Be aware that after weightloss the skin can loose it’s elastic recoil and so revisions are higher in augmentation mastopexy in weightloss patients My approach would be a dual plane implant then anchor scar , for mastopexy , gives the most control on the shape of the breast Make sure who you choose has experience in post weightloss skin removal surgery , FRCS and is a full BAAPs registered plastic surgeon - it’s a benchmark for surgical experience and professionalism.
