Bernand and Marie-France Cohen (the couple behind the luxury children’s clothing brand Bonpoint) now introduce the newest Parisian wonderland. Opened in March 2009, their Marais shop is a 1,500-square-meter designer mecca: a vintage clothing selection bursting at the seams with Burberry coats, Dior jackets and Chanel quilted bags. Teenage girls and their well-heeled mothers, rejoice!

The designer corner cradles pieces created especially for the store by the likes of YSL, Stella McCartney, Azzaro, Alexis Mabille and Marni—and cost 30-40 percent less than from its respective name-brand stores. Upstairs features, at again slashed prices, children clothing from Bonpoint, which alludes to Merci’s other amazingly generous cause: all profits are re-funneled into a children’s charity in Madagascar.
