Ashley Olsen stole the show last night by sporting a head scarf on the red carpet at a party for YSL's new fragrance Belle D'Opium in NYC — what do you make of her look?

Maggie Gyllenhaal and Alexis Bledel, though, kept things simple in one-colored gowns. Ashley attended the bash without her usual companion Mary-Kate, but the sisters were recently together to work on a colorful project. They also rang in their 24th birthday last weekend, and to celebrate Fab took a look back at how their styles have evolved over more than two decades.
