So you’ve picked out your favorite turtleneck options to add to your wardrobe. The next step is figuring out how to layer them.  “When layering turtlenecks, I think the fit is extremely important. It's best to layer body-hugging silhouettes versus styles that have volume,” Cunningham says. “As I always say, your wardrobe tells you how it wants to be styled, and with that said, its silhouette will guide you in finding the best pairings.” In other words, if you opt for thicker, bulkier sweaters, they might be perfectly fine on their own, paired with slim-fitting trousers or mini skirts. If you opt for something more form-fitting, then there’s room to play around with adding a leather jacket, shacket, or another top.  “My go-to is under a blazer or button-down, two super-chic outfit combinations that can do no wrong,” Cunningham shares of her favorite ways to layer.
