It's pretty well known that Heidi Klum has had breast implants. This before and after picture shows how her bra size went from a small A cup to a 36C! That breast size isn't remarkably big, but it's 3 times bigger than what it used to be. In the after picture, her bikini can barely contain her assets!
It's pretty shocking how flat chested Heidi Klum was before breast implants. But overall, her boob job came out terrific because she now has a good bust without being over the top. Her height is 5' 9" which is ideal for a 36C breast size.
