“I don’t have to choose between high fashion or streetwear,” Virgil Abloh once said. “My brand reminds me that it doesn’t have to fit in a box. It can just be in a gray area.” A trained architect, the former artistic director of menswear at Louis Vuitton, and founder of Off White streetwear, Abloh did things his own way. Indeed, he created a language of so-called Abloh-isms and worked from a set of personal “codes”—his characteristic design principles. A new exhibition in Paris traces nearly 20 years of those “codes” through 20,000 archival pieces: prototypes, sketches, objects, images, and garments from his collections. —Carolina de Armas
