Sienna Miller attended a screening of “The Mysteries of Pittsburgh” in New York City back in April wearing a Marios Schwab red dress.

The dress was massively modified from the runway to exclude the crystal-embellishments in the fold-detailed on the bodice and skirt.

Sienna wore her hair in a messy updo pairing her dress with black tights, black peep-toes and red lippie to match her dress.

On Sunday night Cheryl Cole appeared on the “X Factor” wearing the same dress with the sparkling crystals.

She kept her legs bare and added leg-lengthening Brian Atwood platforms.

As much as I didn’t like Cheryl’s hair, I much prefer her embellished dress as it had a bit more pizazz about it so she wins for me.
