Olivia Wilde is on the January 2010 cover of Lucky.

Her fashion alter ego:

Olivia Wilde's alter ego—at least when it comes to fashion—is French: "I find myself constantly pretending I'm a chic Parisian," says the L.A.-based actress. "I even dream of buying a Balmain jacket with really sharp shoulders. If I can pull off that look, I will have succeeded, at least partially, in my quest."

Her favorite bargain haunt:

"Coats from H&M are inexpensive and usually have something extra going on—so even with a simple sheath dress, your outfit is still interesting."
