Rosie Assoulin's mission is never to create anything basic. The garments may be simplistic, but they are always wearable and good-spirited. The 'Accordion' dress features a striking one-shoulder design that exudes modern elegance, while its vibrant multi-colored stripes create a playful yet sophisticated look. Wear the ties as a slash for a sleeveless look, or use the buttons down the sash to create a full sleeve.
