I am a small girl, 5'3" 112 lbs. I have had 550 cc McGhan, Silicone Moderate Profile under the muscle implants for 7 years. I had a concentric lift done at the time. I like my breasts, they are just HUGE on me. I have decided to have an implant exchange with another concentric. I want to go down a full size. I dont know which size/shape of implant to go with. I think Im torn between a 400cc HP or a 375 Mod+, opinions, please. I want a full natural look that fits my frame better.
