Derek Lam 10 Crosby Afloat by Derek Lam 10 Crosby is an elegant floral fragrance for women. The 10 Crosby collection features fragrances inspired by various scenes Derek Crosby witnessed from his New York City office window. It happened on Crosby Street: An escape to a rooftop. Crosby Street overlooking New York City. The shared mischief of being up there. Modern white mimosa evokes the feeling of sunshine on a hint of darker orris.
