I said this was on it's way back. This summer the pegged roll is the easiest way to make slim, straight cuts look extra chic. Janine Chilton-Faust of Levi’s reminds you how to do it. Step 1: Grasp a bottom hem and fold it vertically so there’s a ½-inch tuck in front. Step 2: Hold the tuck in place while you roll up the hem by about two inches twice. Repeat with the other leg.
