For the last day of New York Fashion Week, Calvin Klein creative director Francisco Costa delivered a strong fall collection with a clever mix of masculine and feminine elements. With label devotees Olivia Wilde and Jessica Chastain sitting front row, the designer showed a cool take on modern dressing, with curve-accentuating looks. Appealing to a woman’s tougher side were a bonded vinyl overcoat and head-to-toe leather looks. The outerwear offering proved to be a highlight, with a chic topper for every occasion—from plaid wool (perfect for 9-to-5) to a head-turning sheared alpaca stunner. Sleek platform pumps with gold plaque embellishment and knee-high vinyl boots finished off the streamlined looks. See our favorites in the gallery!
