A classic black turtleneck is a chic staple piece in your wardrobe, perfect for layering under blazers and cardigans. Whether you're heading to the office or out for a casual brunch, a classic turtleneck sweater is an ideal choice. Layer a slim high neck top under a crisp shirt, pair a white polo neck jumper with tailored trousers, or stay cozy in a spacious roll-neck sweater.
