It's hard to imagine a bikini being seen as controversial today, but the bikini was once the most scandalous swimsuit to hit the beach, that is, until they started making those movies with Annette Funicello and Frankie Avalon.
But in the less than 100 years since the bikini made its revealing debut it has gone from a no-no on many beaches to standard gear on just about every beach in the world.
And it's all thanks to bikini pioneers like Nancy Sinatra, who posed in a sexy white bikini with them big ol' boots she uses for walkin'and caused controversy with the bikini photo on the cover of her album Sugar.
But well before Nancy let her midriff breathe Hollywood mega-star Rita Hayworth stepped out of the pool for this shot from 1946 that had everybody offering to be her own personal lifeguard.
Rita led the way for Marilyn Monroe to stun in her two piece suit while keeping it classy as always
And last but certainly not least here's Halle Berry in that sharp orange bikini she wore in Die Another Day in 2002, which comes complete with dagger scabbard in case a Beach Blanket Rumble breaks out.
