Couture eyewear that attracts haute celebrities and British aristocrats is the scene here. Optometrists Graham Cutler and Tony Gross carved a niche for themselves in the early 1970s, creating glasses that weren't merely necessities for the short-sighted, but handmade, stylish fashion accessories. They haven't looked back since. Just down the street, at 7 Knightsbridge Green, is Cutler and Gross Vintage, where you'll find Cutler and Gross vintage specs, as well as YSL, Pucci, and others.
