Sophia Bush, Perrey Reeves and Keisha Whitaker joined Katie Holmes to celebrate Ann Taylor’s Summer 2011 collection at the Château Marmont in LA yesterday.

Sophia Bush wore an Ann Taylor sunburst sheath dress which she paired with a beige blazer. You can see her without the blazer in a picture below.

An Ann Taylor bronze lace cuff, a cross body bag and Christian Louboutin platform sandals completed her look.

Perrey Reeves opted for a bright red halter dress which she teamed with Ann Taylor accessories including a fringed necklace and a pink exotic foldover clutch.

I love the rose gold sandals.

Keisha Whitaker opted for a very casual look with some on trend coloured jeans.

Black Ann Taylor gladiator heels completed her look.
