Sports Illustrated is celebrating the 50th anniversary of its annual swimsuit issue this year. Here, we examine all 50 covers to see how "sexy" has evolved since 1964. Or didn't. (Hint: still boobs.)
In the beginning, the cover shot poses had a much more candid feel — especially compared to recent iterations. Almost like casual snapshots. Another immediately noticeable difference is that in 1964, the first covergirl — Babette March — didn't even fill out the top of her white bikini; in 2013, a parka couldn't even contain all of Kate Upton. However, the belted suit on the 1965 cover established a tradition of regularly featuring swimwear that would leave nightmare tan lines. Some things never change.

While Cheryl Tiegs was the first repeat cover model, Christie Brinkley was the first to land three consecutive covers. Also note how these ladies are very smiley and approachable. Friendly.

Tyra Banks was the first black woman to land the cover in 1996. The '90s was also when the "sexy death stare" started becoming the preferred expression. Fewer smiles, more intense eyes.

It's not like the swimsuit issues are ever about actual swimsuits, but recently that's become even more obvious: Models are typically posed not really wearing them.
