Sports Illustrated is currently in the throes of celebrating the 50th anniversary of its iconic Swimsuit Edition—the magazine just hosted a big bash in New York attended by the likes of Kate Upton and Heidi Klum, among others. We thought that in honor of the brand’s biggest and most successful franchise, we’d take a look back at the sexiest ladies who’ve graced the cover in the 50 years it’s been heating up bookshelves everywhere.
From Tyra Banks in that unforgettable pink-and-red polka-dot string bikini to Upton in what is literally the tiniest bikini yet to be seen by human eyes, the swimsuit edition has long been the foremost authority on beautiful women in skimpy swimwear. And back in 2000, they upped their game even more by debuting a 3-D issue.
