Katharine McPhee celebrated the premiere of her new show, ‘Smash’, in New York City on Thursday evening with Sarah Jessica Parker.

She wore a black and white Donna Karen Pre-Fall 2012 dress with a navy bow sash.

The voluminous dress pairs well with Katherine’s tousled lob, but for the premiere of her own show, I would have preferred something a little more glitzy and a little less aging.

The show is about Broadway, after all.

A stack of bangles and sapphire drop earrings do help the simple look, though.
