From People’s Off The Rack: As the weather gets hotter, we just want our clothes to get easier — and what’s simpler than a dress than can go day to night and requires the bare minimum of accessories? We’ve spotted Eva Mendes, Nicole Richie and Sienna Miller wearing smocked tube-dresses with great bold patterns and long sweeping hems. Just toss on a few bangles, a cool bag and comfy sandals, and you’re set! Dress it up for night time with jeweled flip-flops and an oversize clutch.
