Dear madam, I would have been very helpful to see your front and side view pictures, so that the best outcome from the surgery for your breasts, could have been recommended to you. Be it as it may, it is clearly less costly to have only one side breast augmentation You have to realize that even though cost of surgery is important, choosing the right surgeon is more so, because if corrective surgery is necessary, the cost will escalate significantly. Another important fact is that not all result are the same, because experience, skills and aesthetic eye are critical for good and safe outcome. So do your due diligence and choose wisely. Always, consult with experience board certified plastic surgeons who operate in accredited surgery center for your safety. Most importantly, check the before and after pictures in the phoyo gallery, to make sure that they are numerous, consistent and attractive. Best of luck, Dr Widder
