This shop—actually a collection of small shops—was a pioneer designer boutique in the 1970s and continues to talent-spot the newest and best around. You may find the windows showcasing the work of top graduates from this year's student shows or displaying well-established designers such as Erdem, Dries Van Noten, or Balenciaga. The men's store at No. 23 has a similar designer selection, while Browns Focus at No. 24 showcases youthful, hip designs and denim. There is a smaller boutique on Sloane Street and if you're about to go down the aisle, check out the two bridal boutiques; one at 12 Hinde Street, which stocks various designers, and another at 59 Brook Street devoted to Vera Wang gowns exclusive to Browns in the U.K.
