Gwen Stefani worked a monochrome look for an outing in LA. She rocked her trademark blonde hair simple with a side parting adding some red lipstick for a touch of glamour. The fashionable star wore black harem trousers that gave a relaxed silhouette. It seems her style was catching as the Stefani's husband Gavin Rossdale also chose to wear a pair of harems. He styled his baggy bottoms with a white tee and denim shirt.
