Olivia Wilde attended the World Premiere of her new movie, “Cowboys & Aliens” during Comic-Con 2011 on Saturday in San Diego, California.

She looked very pretty wearing a sheer Dolce & Gabbana black floral embroidered gown.

My first thought was that this look aged Olivia, but her sleek ponytail and smoky eyes helps to prevent that.

Carrera y Carrera jewels and a gorgeous smile completed her look.
