Sagging Breasts Age 19. Lift? Teardrop Implants? (photo)

I'm 19 years old and have always had large breasts at the age of 13 I wore a size 34G. As of recently lost around 40 pounds due to healthy eating and exercise. I have always had an issue with sagging but even more so now that I've dropped down to a 34DD. Although I'm a 34DD my breasts aren't full and are actually very small. I have a lot of excess stretched skin and not a lot of mass in my breasts. I want to have a lift but also want to obtain a look of perfection with a teardrop implant. HELP
