Here’s a fashion riddle: what’s green and oversized and has been all over? Jessica Simpson‘s favorite sweater! “That sweater has been through a lot,” the singer, who’s been photographed rocking Theory’s cozy Juliette sweater since 2005, told PEOPLE in March. “It’s my magic sweater!” Simpson has paired the top with everything from leggings to jeans to sexy heels — and has worn it at the grocery store, at the airport and everywhere in between. The one occasion paparazzi haven’t captured her rocking it? “I like to wear [it] with just underwear around the house,” she giggles. According to Simpson, when she wants to feel beautiful and relaxed, oversized clothing is the way to go — and when her go-to top is dirty, she hits fiancé Eric Johnson’s closet. “I wear his Yale sweatshirt all the time or some of his 49ers gear, but it goes down to my knees,” she says. “But I do love wearing men’s clothes. I think that’s sexy.” —Lesley Messer
