Katie Holmes tried out a new look last night at the New York City premiere of "The Extra Man."

In sharp contrast to her signature sleek chin-length bob, Holmes arrived (without hubby, Tom Cruise) showing off messier, shaggier hair. Her tresses, which have been getting longer this year, were styled in a care-free manner with loose waves throughout and heavy bangs swept off to the side.

Cute, but is it movie premiere appropriate?

The 31-year-old actress paired her casual 'do with an even more casual outfit: a navy-and-red striped Celine t-shirt dress and Roger Vivier black short heel pumps adorned with a buckle on top.

Maybe she was trying to match the lightheartedness of "The Extra Man," a comedy-drama opening July 30 where Holmes appears alongside Kevin Kline and Paul Dano.

What do you think? Is Katie's look red carpet ready or better suited for playdates with Suri?

Take a look at another striped -- and much more sophisticated -- dress that Holmes recently wore.
