If you think that Kim Kardashian's recent bondage-inspired bikini was out there, you will be pretty shocked by how innovative - and outrageous - swimsuits were in the 1950s, '60s and '70s, thanks to avant-garde designer Rudi Gernreich.
There were the common, conventional bathing suits of that time, and then there were Gernreich's swimsuits. The Austrian-born designer's wildly fantastic inventions included the first topless bathing suit, the pubikini (a swimsuit that intentionally revealed pubic hair, so warning: that's an NSFW link), the thong swimsuit, the monokini (a one-piece swimsuit that reveals the breasts) and the "No-Bra Bra" (made out of two sheer triangular pieces of fabric).
Gernreich's legacy, which was recently celebrated with an exhibit at MOCA in Los Angeles, hasn't been forgotten -- just take a look at our recap of Miami Swim Week 2013 to see how outrageous contemporary swimwear can be. Gernreich-inspired topless swimsuits and monokinis are still considered shocking today.
Longtime California resident Gernreich died in 1985, but we're celebrating what would have been his 90th birthday on August 8th in the most befitting way possible: by looking back at some of the weirdest, wackiest and most iconic swimsuits of all time. Take a peek in our gallery below and let us know: which is your favorite?
