Currently 4 months post op BA/BL 450cc HP mentor implants. As time goes on I feel I’m loosing upper pole by the day and without a bra I’m almost staring to look flat chested due to the gap in the middle. I have to wear push up bras that add two cups sized just to look full. My skin is too loose to even wear sticky smallness bras. What implants would help me achieve a more fullness, upper pole and more cleavage. XHP 650/700?!?!?
