A sure sign of warm weather: stripes are suddenly everywhere. I personally couldn’t be happier, especially when they arrive in the form of the Marc by Marc Jacobs Striped Summer Tote. This could be my favorite casual bag of the moment. It’s fresh and sporty, with an effortless look that makes it cool enough to carry everywhere from a picnic to the beach. You can’t go wrong with its functional side, either; it’s designed to perform, with pocket space and a spacious interior. Available for $228 at Neiman Marcus.
