A.P.C. Atelier de Production et de Création's 'Iggy' pants are one of those core staples that you will reach for time and time again. Impeccably cut in a flattering straight-leg silhouette, they're made from cotton-twill that's woven with a hint of stretch for a smooth and comfortable fit. Wear yours with slim turtlenecks to the office, switching to the label's floral-print blouse at the weekend.
