Tinsley Mortimer attended the 2011 Whitney Museum Of American Art Studio Party in New York City this week.

The socialite wore a gorgeous Versace Fall 2011 gown.

Her deep-blue one-shoulder gown with a full-feathered train is part sexy, part fun, part divalicious.

Strappy platform heels, a silver clutch and a black clutch completed her look.

A much smaller clutch would’ve been preferred.
