Perky boobs?

Courtney

So I’ve recently lost over 35lbs🙌🏼🙌🏼 and my breast have gotten smaller. I was a 38DD now I’m a 34DD and they are really saggy and I need tips on how to get them perkier I’m only 20 so this really bothers me to be so young and have saggy breast also with a lot of stretch marks (need help with that too). What ways is there to get my breast naturally perkier.
