During the summer, lesser is better. Less makeup, less clothing, you get it. That also applies to what you carry, because that giant tote isn't doing you any favors when you're on your way to the beach or a festival. When you're a weekend warrior and stack your summer Saturdays with plans, you need to be able to move freely -- and keep your hands free for photo-snapping, latte-sipping and impromptu dance parties. So ditch the purse and put your essentials in decidedly the cutest carry-all that exists: a miniature knapsack. A full-sized backpack will just make your back sweat, but these little guys keep all your valuables in an easy-to-reach place and can really complete a look.
