Thom Browne leads the American luxury market, and with these 12 carat gold plated sunglasses, it's easy to see why. They're a squared off aviator, complete with a gold brow bar, but the decadent, vintage-look shape becomes elegant with delicate proportions. As ever, Browne's intense attention to detail is paramount, with his four bar branding engraved into the gold nose pads, and enamelled tricolour tips.
