I was so similar to you. Had asymmetry and borderline needing an uplift before my surgery. I was due to have 475cc and 500cc high profile overs but in the operation they couldn’t fit the larger implant in so I got 425cc and 475cc. I’m really glad I didn’t go for the uplift as I have a great result. The implants have really filled out my breasts, they’re a really good size and they’re definitely not saggy looking at all. Obviously though all boobs will eventually sag, and as we have larger sized implants I have to be realistic to know that I may need an uplift in the future to keep them looking high, but I would rather do this when needed.
The choice is completely up to you but in my case I didn’t have the extra money for the uplift right now so I trusted my surgeons advice and couldn’t be happier x
