WHY WE LOVE IT Inspired by the classic ballerina bun, this ultra-chic top knot is strong and sexy.
HOW TO DO IT1. To achieve a sleek look, dampen hair from roots to ends with a frizz-fighting mousse. 2. Smooth strands back into a high ponytail on top of the head and secure with an elastic. 3. Wind the ponytail into a knot that's shaped in an oval, not a circle. "This softens the overall look," says Hilary Duff's stylist, Marcus Francis.
