The Great White Shirt

Stacy says there are many great ways to incorporate a white shirt into your wardrobe. First up is a crisp way to incorporate color. "We have a great J. Crew cashmere sweater over that," she says. "The reason we can do it over is the shirt is [that it's] fitted, so there's no bulk."

Paired with a dark trouser jean and colorful accessories, the white shirt sheds its buttoned-up, serious stereotype. "It's young, but it's not too young," Stacy says. "It's more energetic."
