Cheers to Oilvia Munn for being resourceful.

Wednesday, the sexy actress hit up Us Weekly's Hot Hollywood party — where she was honored as the 'Sexy Tomboy'— and didn't need to raid her stylist's closet to make a splash. No, all she needed was a $30 ASOS dress.

"I didn’t quite think about my style until I got that call," she said. "I want to look and feel effortless."

We think she pulled it off.
