Rudi Gernreich, arguably most famous for the topless swimsuits he launched in the 60s, was a driving force in the sartorial revolution of the 60s in the U.S.
I have read that Gernreich's topless suits launched the topless beach craze, though I have also read that the swimwear was not a commercial home run. Not so, his famous 'No Bra', which was a best seller from Day One.
It seems so mundane nowadays; a sheer bra with no wire or padding. At the time, it was nothing short of revolutionary. Bras before this were made to change the shape of a woman's breasts; not celebrate their natural shape.
But Gernreich also designed more than swimwear and underwear.

A quasi-famous video of Peggy Moffitt sporting Gernreich looks, filmed by Moffitt's husband, longtime collaborator of Gernreich's, photographer William Claxton, called 'Basic Black' is said to be the first fashion video.
