Time for some straight talk—everyone from Angelina Jolie to America Ferrera is donning pencil-thin pencil skirts for a sleek look. But do not fret the sheath style if you have a less-than-perfect body. "Hippy?" Project Runway's Tim Gunn told In Style. "Pair a tight skirt with an Empire top to the hip bone. Looks so chic!" Curvy types like Ferrera look best in 50's-inspired ensembles with a nipped-in waistband. "I'm in favor of the cinched waist," Gunn said. "You can't do it with a big tummy, but if you're hippy, busty or have a thick waist, cinch it!" The result? A ladylike look that emphasizes your curves.
