Back in the good old clothing-optional days of ancient Greece, Olympic athletes competed in the buff. It was a dress code that enhanced both the quality of sport--the long jump isn't exactly toga-friendly--and spectatorship. Of course, the custom has since fallen by the wayside. Still, even with their clothes on, Olympians are an awe-inducing sight. From the gymnasts with their compact bodies and dancer's grace to the lean and sinewy long-distance runners to the brawny soccer players, the Games' female competitors stand as reminders that feminine beauty exists beyond the oft-touted 36-24-36 ratio. And with a little help from Playboy, swimmer Amanda Beard has even shown that today's Olympians look just as good naked as the ancient Greeks.
