Long, sleek and sophisticated, this dress offers an unusual take on classic black evening wear. The Alexander Wang Women's Moving Rib Long Sleeve Dress in Black is modestly cut, with long sleeves that reach the wrists and a skirt that drops to the ankles. A small slit runs up the centre back of the skirt, but only as far as the knees. Made from a comfortable, ribbed knit fabric that is easy to wear, this dress features relaxed raglan sleeves. The ribbing runs in different directions on the sleeves and bodice, and a triangular point at the centre front adds some visual excitement. An unusual, enticing detail is added by the silver zip that runs across the boat neckline, which can only be seen as you get close.
