The midtown flagship has often been compared to a Chanel suit -- slim, elegant, and timeless. Inside wait the famed suits themselves, along with other pillars of Chanel style: chic little black dresses and evening gowns, chain-handled bags, and yards of pearls. Frédéric Fekkai's five-story, Provence-saturated salon perches upstairs. Downtown's branch concentrates on more contemporary forays, including ski gear, while Madison's boutique is dedicated to shoes, handbags, and other accessories.
