This is unofficially the last week of summer (BIG HUGE HEAVY LOUD SIGH), so that means it’s time to start budgeting for your pumpkin spice lattes, pulling the old rake out of retirement and storing lightweight tees and tanks in the back of the closet. The plus side is that bags like the CoSTUME NATIONAL Colorblock Piccola Messenger start to become commonplace. I love everything about this, from the vivid purple hue to the sporty shape to the utilitarian strap. It’s the perfect complement to your fall wardrobe. Available for $1480 at Bloomingdale’s.
