Marilyn Monroe is looking spectacular in this oh-so retro black and white polka dot swimwear. This photograph was taken in 1951, and was one of the many photographs that was on show at Marilyn Monroe exhibition in 2012. Well, if going totally retro is not up your alley, then take inspiration from actress Nina Dobrev's athletic beach look. If you wear your heart on your sleeve and can wear polka dot beachwear with confidence there is nothing like it!
