Jacquemus - Baya Cutout Cotton-blend Turtleneck Sweater - Navy

If you follow Simon Porte Jacquemus on Instagram, you'll know he recently stayed at Pierre Cardin's villa, Palais Bulles - this 'Baya' sweater has three cutouts at the back resembling the iconic building's sculptural curves and circular windows. It's knitted for a close fit from a lightweight navy cotton-blend and has a ribbed hem. The coolest way to wear a turtleneck this season is with big earrings.
