A playful ode to debutante balls and party looks from the 1980s, the Mireya dress from Stella McCartney is the retro-inspired LBD you need. Crafted from black crêpe, the V-neck style has a slim-fit bodice and skirt, which is countered by the voluminous taffeta sleeves. Accessorise yours with jewel-toned pumps and an embellished bag for your next soirée.
