WHO'S WEARING IT Emmy Rossum
WHAT MAKES IT COOL It's incredibly versatile. Wear it clipped to the side like Rossum, or woven into a loose braid. "If you've been working all day, twist a section back and it's an instant night look," says her stylist Frank Galasso.
GET IT (DON'T SWEAT IT!) 1. Work a dab of de-frizzing cream into damp hair and blow 85 percent dry. (You don't want your hair too stick straight.)
2. Part on the side and wrap random sections around a 1 1/4-inch curling iron. "For more modern results, don't use the barrel's clip," says Galasso.
3. Twist and pin waves to the side.
