We’ve been wowed by the recent makeovers of two luxury powerhouses. First, Chanel moved from its No. 5 Newbury address to No. 6, expanding to a 10,000-square-foot space designed by acclaimed architect (and certified character—Google him) Peter Marino. Coco herself would approve of the design, meant to channel her Parisian apartment—picture Swarovski-covered deer by artist Mark Swanson and sofas decked out in Chanel tweed. Not to be outdone, Valentino revealed its own new look in June, becoming the fourth U.S. location to boast the design concept from Stirling Prize winner David Chipperfield. Intended to evoke an intimate palazzo, it’s rich with Venetian terrazzo, thick leather and plush carpets; ambient lighting and chandeliers let the ready-to-wear, handbags and shoes shine. Now Boston’s chicest block looks even more glam.
