Few things beat the simplicity of a summertime romper. You just throw it on and go. The look requires minimal effort, almost no thought, and very few accessories. The genius of a playsuit is that it's not only easy, it's practical, too: Unlike a skirt-and-top combo, the one-piece look allows you to a bike, picnic in the park, and do other fun warm-weather activities without worrying about your outfit. Sienna Miller, who surely knows how to have fun, gets it. Yesterday in New York City, she wore a floral Topshop number neatly cinched at the waist with a wide, suede belt. Simple ballet flats and a handbag in matching black suede was all it took to turn a single item into a whole look. This weekend, when you’re too busy — or, considering the weather forecast, too hot — to mess with separates, reach for a little patterned playsuit. Then go play.
