Through the decades, the mighty polka dot has fallen in and out of fashion favor. The dot has made its way back in this year, as singers, actresses, Michelle Obama, sports stars, and even cartoons, flaunt the look . Most recently, there’s been a frenzy over Taylor Swift’s red polka-dotted bikini that she’s been wearing around Cape Cod this summer. Meanwhile, Katy Perry’s fashion interpretations never fail to raise eyebrows, and the celebrities of yesteryear who rocked early polka dots made the look famous: Think Marilyn Monroe‘s character in the 1955 film “The Seven Year Itch” and the real-life Jacqueline Kennedy Onassis vacationing in Italy in 1962.
