>> The iconic little dot. A favorite of the fashion set since in the mid-1700s (when it was worn by late-Rococo aristocracy), spotted prints were christened "polka dots" in the 1840s as polka music captivated the world. Since then, the popularity of the graphic little dots has only grown; in 1940, the print was so omnipresent that The Los Angeles Times remarked, "You can sign your fashion life away on the polka-dotted line, and you'll never regret it this season." One won't regret it this season either — especially when it comes to pants. In every incarnation from palazzos to clam-diggers, dotted bottoms have been showing up on runways steadily for the last three years. Here, we track the trend from Louis Vuitton's 2009 slouchy silk versions (precursors to today's popular pajama dressing perhaps?) to recent sightings on the Resort 2012 runways.
