Oscar de la Renta's striking red dress was designed to flatter: it has a slim silhouette, a nipped-in belted waist and an A-line skirt that highlights the body's curves. Crafted in Italy from wool crêpe with a touch of stretch, this number has demure 3/4 length sleeves and falls to knee length for a style that's appropriate for a multitude of occasions. Complete the look with classic pumps and one of this season's must-have mini bags.
