Are some implants "better" than others?

"I have small breasts, obviously," Kate Hudson said at the 2002 Golden Globes. "It's nice to be able to wear a plunging neckline and have it be elegant."

In fact, many fashionable ladies with small frames have small breasts, and prefer them that way to obtain a certain look in designer clothes. But US Weekly is reporting that 30-year-old Hudson was tired of her flat chest. An insider says she received a minor breast augmentation in late March. You can see her cup size has grown in the photo on the right, taken in Miami on April 9. The photo on the left was taken last year.

"Kate makes jokes about her boobs, but her chest has always been one of her biggest insecurities," says another source. And we would understand why a woman who has a flat chest would long to have a bit of curves on her. So far the reaction to Hudson's boob job has been a positive one.

While the 23-year-old "Hills" actress already received one set of implants back in 2007 (she went from a 32A to a 32C), she recently got a major upgrade. Her breasts are now a DDD, and she wishes to go up to an H for Heidi, but doctors have informed her that her body can't take that amount of silicone. At least not yet. Perhaps for some people, breast implants are like tattoos--you always want more. Or maybe, like Kate Hudson, Heidi just wanted a more curvy figure to make herself feel better.

Montag has been criticized left and right for her excess of plastic surgery, but when it comes to implants, are some procedures "better" than others? Do we hate on artificial looking breast implants more realistic ones? [US Weekly]
