Dear rdrs, Thanks for submitting your pictures and sorry for your problem. From observing your pictures, you appear to be full C cup size with significant double bubble defoermity. Most likely, you had mild to moderate ptosis before surgery and your surgeon tried to create perkiness by lowering the sub mammary crease , which did not stretch , creating the double bubble deformity. Going bigger is possible, however, before doing so, you will need to correct the double bubble deformity with inferior capsulorrhaphy (internal bra) and, most likely mini lift procedure (donut, Benneli) , in order to give you beautiful perky breasts. These procedure will make the breasts appear bigger, so that you will not need to go with 600 - 650 cc , because heavy implants increase the risk of relapse of the double bubble due to the downward pressure. Going to 500-525 cc, most likely will suffice to bring to full D cup size. Always, consult with experienced board certified plastic surgeons who operate in accredited surgery center for your safety. Most importantly, check the before and after pictures of redo breasts augmentation in the photo gallery, to make sure that they are numerous, consistent and attractive with nice cleavage and sub mammary fold, perky, symmetrical and natural looking. Best of luck, Dr Widder
