Hi, I'm interested in having a breast augmentation and after much research I've decided I would like to go with silicone. I am 5'3 105 pounds, and heard silicone works best for someone with minimal breast tissue. Of the three major manufacturers on the market, I prefer Sientra because they seem to be the most "cohesive" when cut in half and they come with an awesome warranty.... So, are they available in Toronto? Thanks.
