It was a fashionable double whammy for Ellen Pompeo yesterday.

Last night she attended the “American Cancer Society’s Choose You luncheon” at Cafe SFA at Saks Fifth Avenue in New York City.

She opted for a smart but casual Lanvin denim dress from the Resort 2010 collection which I absolutely adore.

The “Grey’s Anatomy” actress swept her hair to one side so we could appreciate the denim rosette corsage on her shoulder.

I don’t usually associate Lanvin with denim, but this is a refreshing take on their trademark one-shoulder style dress.

Pink Sergio Rossi heels complete the look.

Earlier in the day Ellen hosted the American Cancer Society’s launch of the ‘Choose You Movement’ in Time Square, New York.

She looked very presentable and event appropriate wearing a Stella McCartney frilled peplum jacket from the Spring 2010 collection.

You may remember her former co-star Kate Walsh wore this same jacket a few weeks ago.

Ellen completed her look with a simple white top, a grey skirt and beige Sergio Rossi heels.
