When bangs are working, they're the best accessory a girl can have. Jennifer Lopez's soft, graceful bangs are the perfect solution for many women. A longer graduated bang is flattering and flexible, yet still makes a statement.

Severe rarely works. Mena Suvari's beauty is completely overwhelmed by the severity of these stick-straight bangs and bob. The bangs are also too narrow, crowding her face. Very few faces can get away with this kind of look, and even the lovely Suvari can't.

Retro headbands are making an appearance all over Hollywood. Milla Jovovich is a retro master. Her delicate headband is the perfect accessory to her retro hairstyle without looking like a costume. Keeping the headband simple yet giving it center stage and limiting the retro factor to one or two elements in the look is what makes this work.

Paris Hilton makes all the classic retro look mistakes. The size and placement of her headband completely overwhelms her look. Combined with lots of makeup, platinum hair, and a costume-y beaded dress, this look would be more at home on a Broadway stage.

Victoria Beckham is gorgeous, but that doesn't mean she's the only one who can pull off this look. This cropped bob with wispy bangs is flattering for most face shapes and is easy to style too.
