Joan Burstein, who has been called the fairy godmother of fashion designers, fills her South Molton Street boutique with the most-wanted collections from fashion’s elite. Lanvin, Alexander McQueen, Balenciaga and Gareth Pugh are just some of the names stocked here. Alongside dresses that run the gamut from tough and bohemian to futuristic, you’ll find an abundance of well-cut tees and directional denim. This is the place to get a head start on next season’s trends.
