To mark the opening of their new Avenue Montaigne flagship in Paris, Saint Laurent has created a “permanent collection” which they plan to house in their gleaming marble museum store. Like other label’s “commercial pieces,” the company has taken classic items with inherent brand DNA — Le Smoking, a leopard print coat, a duffle bag, crepe de chine blouses in black and white, a motorcycle jacket — and committed to producing them all year long, the better to pair with the house’s trend-driven seasonal collections. Designer Hedi Slimane, a photographer himself, shot the classics on Freja Beha Erichsen (we assume because Courtney Love was deemed too trendy), then shared the campaign exclusively with the Cut. Ah, permanence. Because what’s the point of having best-sellers if you can’t keep selling them for years to come?
