I would bet that more women (and models) than you think have breast implants. A talented surgeon can make implants appear extremely natural. I work in plastic surgery for a living, with clients ranging from a Hawaii cosmetic surgery practice to a Saratoga Springs breast enlargement surgeon, and I'll be blunt: I've seen a lot of breasts. Yes, some women prefer that clearly-enhanced look, but I've also seen women who have practically no breast tissue to begin with and through augmentation surgery achieve a very "normal" appearance, using both silicone gel or saline implants. It really is all about the surgeon's skill and the decisions that go into the surgery - how big the implants are, implant shape, implant position, etc. I am certain that Vicky's Secret models would only go with the best.
