Keri Russell is on the March 2010 cover of Lucky, her new movie Extraordinary Measures is in theaters now.

On the evolution of her style:  “I’m into the sexy masculine thing. All the clean lines and tailoring are so classic,” says the actress. “I look for those details on dresses and skirts, too.”

The March issue of Lucky is on newsstands this week.

For some reason I needed a couple minutes to figure out if Keri Russell’s dress here is flattering or not. A loose, sleeved dress seems pretty irregular these days for cute starlets.

But the short white drapey dress and the wavy hair make for a perfect combination of girly and grown-up.

Russell hit the red carpet in Los Angeles Thursday for the premiere of Bedtime Stories.
