The British actress stayed comfortable in the breezy autumn weather wearing a Alessandra Rich off-white drape silk dress with open sleeves, from the designer’s Spring/Summer 2012 collection.

She left her long blonde hair out in natural waves before finishing off with a red lip-shaped bag with a gold thin chain strap. The longer length of her dress prevented us from seeing which shoes she selected.
