With its sleek, polished leather and aquamarine dark-green fur, Alexander Wang's Prisma tote serves as quite a specimen, catching the eye of any flora-fauna enthusiast. She has an unfussy, streamlined look and loves collecting baubles from nature: geodes, fossils, butterflies, and other creatures, naturally gravitating to the pattern of things under a microscope. On any ordinary day, she's out exploring in Mango's soft corduroy trousers paired with Madewell's crisp tuxedo shirt and Zara's motorcycle bootie. She tops it off with a dark-green, lablike coat, like this wool-blend one from H&M. And because she can't resist the idea of a little world within a world, a diamond-shape terrarium is her version of utopia.
