After siblings Allison Julius and Louis Marra successfully opened their first luxury lifestyle boutique in the Hamptons in 2008, they decided to bring it to Park Avenue. But don’t expect hoity-toity French country home decor: Maison 24 contrasts the typically traditional taste of its clientele by introducing edgier, surreal designs and embracing disco culture. The store’s interior makes a statement with illuminated white shelves, shaggy carpets, a graffiti-covered phone booth and a black brick wall displaying framed Anton Perich photographs capturing Studio 54’s glory days. It’s a trove of the best and unexpected knickknacks, offering accessories ($28–$2,200), artwork ($1,400–$25,000), clothing ($85–$140), music ($25–$75) and even toys ($145–$600). You’ll find plenty of one-of-a-kind goods, such as a Jimmie Martin hand-painted throne-style chair ($4,250) and a psychedelic cushioned bench ($3,800). Take advantage of wallet-friendly pieces, including house-label velvet pillows with feather designs ($145) and scented candles ($38), as well as Alexandra von Furstenberg rectangle vases in rainbow colors ($310).
