Hi Doctors, I had breast augmentation last April 2019 with Mentor Siltex round high profile 275cc implants in both breasts. My underbust measures 30 inches or 76cm. I wonder if I can achieve cleavage as my breasts seem far apart. Can I get bigger implants now, even with thick skin? Five years have passed. Backstory: Before the surgery, the doctor said he could only use 275cc due to my thick skin.
