Why is it that the word 'polka dots' immediately brings to mind Minnie Mouse and people under the age of five? Far from being juvenile, polka dots are popping up this spring as a sophisticated print for the post-secondary set. First spotted in British fashion in the late 19th century, the polka-dot has endured the ebb and flow of fads. According to Wikipedia, when polka dancing was all the rage, there were many other "polka" wearables, including "polka-hats" and "polka-jackets," but only the "polka-dot" fabric pattern remained popular. Who knew? This vintage photo from Harper's Bazaar exudes timeless appeal and impossible glamour with a simple dotted sash around the waist. Meanwhile, Marilyn and Madonna show off the playful, flirtatious side of dots.
