Katie Cassidy Hairstyle

Anne Hathaway is sweetness personified with her messy-in-a-cute-way 60s' ponytail and geeky glasses. Who says a low-maintenance look can't be chic?

Get her look: A day-old hair works best -- spritz hair with beach spray and scrunch hair with a diffuser to add texture. Then pull hair back into a high ponytail, leaving face-framing pieces down around the face

The trick to touchably sexy waves is shine and body a la Anne Hathaway's beautiful mane. To coax volume and shine, consider investing in a mixed-bristle brush, and brush through strands as you style.

Get her look: Make a middle part and blow-dry hair straight. Take a large-barrel curling iron and curl sections away from your face. Finish with a mist of shine spray.

"Bride Wars" star Anne Hathaway does a modern take on the '50s flipped 'do, complete with teased height and a satin hairband at the New York City premiere.

Get her look: Straighten hair using a flat iron. To create the flipped ends, blow-dry using a small round brush -- curl ends outward and set the style with a blast of cool air before releasing. Add height by teasing roots at the crown, then slip on a sleek hairband.
