Ashley Olsen & Katherine Moennig Both Opt for Black at Hammer Museum's Gala in the Garden

Ashley Olsen wears a pop of turquoise color while attending Hammer Museum’s Gala In The Garden with generous support from Bottega Veneta on Saturday evening (October 11) in Westwood, Calif.

The 28-year-old actress and fashion designer was joined by Glee‘s Jane Lynch, CSI‘s Marg Helgenberger, Ray Donovan‘s Katherine Moennig, and Bored to Death‘s Olivia Thirlby.

Proceeds from the Gala will go to support the Hammer’s dynamic and nationally acclaimed exhibitions and public programs. What a great cause!

FYI: Olivia is wearing a Bottega Veneta dress, clutch, and shoes.
