Sports Illustrated's annual swimsuit issue is eagerly anticipated each year, as the world waits to see which sexy star lands the coveted cover. Our bets are on Chrissy Teigen for the title this year, which is even more exciting than most since it's the 50th anniversary of the magazine's bikini-filled special. The very first woman in a swimsuit hit the cover back in 1955, but it really all started in 1964 with a white two-piece — since then there have been plenty of reasons that the Sports Illustrated swimsuit issue made headlines. Scroll through to see all 50 covers since 1964 — and that one from 1955 too — and check back next week when the cover star is revealed!
