Even knowing you are 5'5" tall, weigh 115 lbs., and wear a 32 A bra, measurements and examination will be needed to answer your question with any degree of certainty. You would also likely find that several consultations with ABPS-certified plastic surgeons who are also ASAPS members and do lots of breast surgery will yield different opinions, so it might be wise to do just that. Get several opinions and see what makes sense to you, along with looking at lots of before and after photographs from the surgeon you might ask to perform your breast augmentation.As a general answer I would suggest the latest generation of cohesive silicone gel implants, smooth round, submuscular placement, appropriate inferomedial partial muscle fiber release, meticulous technique for minimal bleeding, bruising and no-touch Keller Funnel implant insertion for the least risk of capsular contracture. Profile should be in accordance with size choice, then selecting the width that most closely approximates your pocket base diameter to within 1 cm of the midline on each side. Any closer and you risk symmastia (uniboob). For more information you can start by clicking on the web reference link below for my Comprehensive Guide to Breast Augmentation. Best wishes! Dr. Tholen
