Katie Cassidy, the newest addition to the ‘Gossip Girl’ cast for season 4, was spotted in New York City filming a scene with the dashing Chace Crawford.

They both look very smart, no doubt going to a society party in this scene.

Katie wore a Bibhu Mohapatra Fall 2009 strapless gown.

The printed chiffon gown which drapes down the back has a gold band around the waist.

Purple accessories including a Nancy Gonzalez crocodile clutch and Brian Atwood ‘Maniac’ pumps complete the look.

I like the clutch. Not sure about the shoes, but I know I don’t like the necklace.

It feels like one thing too much when so much is going on with her look colour-wise.
