In my mind, great outfits boil down to the alchemy of proportions (i.e., tight with loose silhouettes). Bianca Brandolini d'Adda nails it in this picture, taken in Milan last fall. Okay, it helps that she's a beautiful Italian aristocrat, but her outfit undeniably exudes effortless chic, from her tousled hair and half-tucked-in top to her peekaboo flats and practical tote. Just goes to show how the most simple outfit can be the best outfit.
