At J.Crew, a late-season collection has arrived that is all about stripes. This is the classic bold pattern that originated in Brittany on the coast of France, inspired by sailor’s uniforms and always perfectly in style. J.Crew’s navy-and-ivory peasant top goes with anything — shorts, white jeans, or a flirty skirt. A red-and-blue T-shirt dress is just the effortless look you want in August. And a cotton-blend sun hat is the chicest way to shield yourself from the rays.
