Even though it wasn't her shindig, we find it hard to believe the actress wasn’t the center of attention in her red lace Style Stalker dress which was seksily laced up at the waist.

Emma completed her flirty fiesta fashion with red Salvatore Ferragamo flats and a black Jerome Dreyfuss perforated tote.
Party on, girl!
