STREET OF DREAMS: Rue Cambon in Paris, whose most famous resident is Chanel, is also home to smaller brands. Heimstone, a French label founded by designer Alix Petit in 2007, has opened a 750-square-foot boutique at No. 20 in a former cheese shop, preserving its original tile floors. It’s the brand’s second outlet in Paris for its rock ’n’ roll-tinged clothes and accessories. The unit also carries fashions by the label Three Seven.
