Clearly, Sienna Miller Was Not Going to Be Upstaged by Pippa Middleton

Attending the same gala party as Pippa Middleton in London last night, Sienna Miller decided to break out an eye-catching red number of her own. She wore a scarlet Matthew Williamson minidress, copiously embellished with feathers and sequins. She paired it with beige heels and a bronze clutch.

While this look is certainly all about the dress, should Sienna have tried to coordinate her accessories a little better? (Also, does the ensemble warrant a sleeker hairstyle, or do you like how she brings a touch of undone ease to such a fancy frock?)
