Christian Dior once said that a woman could wear black at any time, any age and to (almost) any occasion. To that pearl of wisdom, we’d like to add that black also works in any weather. Take Prada’s city shorts: worn with Ganni’s bucolic puff-sleeved blouse and flatform sandals, they’re both pretty and practical for a warm day. But pair them with The Row’s high-neck blouse and Stella McCartney’s minimal mules, and they transform into an ultra-cool desk-to-dinner outfit. Black magic.
