Dawn Olivieri and Brea Grant are gearing up for a busy fall season, but this isn’t keeping them from having fun during the summer. Both ladies were spotted at the NYLON + Volcom celebration of the August Denim Issue hosted by Olivia Wilde at the SkyBar at the Mondrian Los Angeles on Wednesday, July 27th, 2011 in West Hollywood, California.

Dawn donned a black Ulla Johnson silk dress that she accessorized with some stunning turquoise jewelry while Brea went for an ultra sexy look in a form hugging Naven ensemble.

Both ladies can be seen on Showtime this Fall when all the hot new shows return/premiere. Olivieri, known for her work on Heroes and True Blood is set to star in the comedy, House of Lies. She will play Don Cheadle’s pill popping wife in this show about a self-loathing highly successful management consultant from a top-tier firm who is never above using any means (or anyone) necessary to get his clients the information they want.

Brea, who also starred on the NBC defunct superhero drama Heroes, is gearing up for her guest starring role on the network hit Dexter. She will be rockin’ a white lab coat while playing intern to pervy Masuka (C.S. Lee).

I can’t wait to see how that dynamic plays out!
