Alessandro Dell'Acqua crafts No. 21's diaphanous black, white and yellow chrysanthemum-print dress from whisper-weight silk for an elegantly airy feel. This Italian-made piece has a self-fastening neck, elbow-length sleeves and a floor-pooling hem. The elasticated waist lends definition, while the additional black crepe slip ensures opaque coverage and a beautiful drape. Wear yours to a balmy evening soirée with tassel-trimmed accessories.
