These days, bikinis are the norm for a day at the beach. The classic two-piece swimsuit for women was first designed in 1946 by French engineer Louis Reard (let’s face it — finding the right fit is a science!) but really came into vogue in the 1960s, with stars like Brigitte Bardot, Rita Hayworth, Raquel Welch and many more rocking this sexy yet sophisticated beachwear option.

 

But which celebrities have sported the most iconic bikinis over the years? This roundup takes a look back at some of the most iconic bikini looks, just in time for National Bikini Day.

 

Rita Hayworth

 

Celebrated dancer and actress Rita Hayworth is best known for films like “Gilda” and “Covergirl” but she was also a big fan of bikinis and burgers. Check her out soaking up the sunshine on the beach wearing a bikini while taking a bite out of a juicy hamburger. (She's got the right idea.)

 

Raquel Welch

Raquel Welch’s iconic cavewoman bikini costume in the film “One Million Years B.C.” had to be on our list of the hottest bikinis of all time. It even looks like it provided some inspiration for the outfits in the music video for “Survivor” by Destiny’s Child.



Brigitte Bardot

Halle Berry
In the 2002 Bond flick, “Die Another Day,” Halle Berry turned heads in this stunning two-piece playing Jix.


Marilyn Monroe

Marilyn Monroe certainly looks like she’s having a ball of a time on a beach near her home in California. Only an icon like Monroe could make a cartwheel in a bikini work.
