The weather outside is frightful, so all the more reason to up your layering game. Thermal leggings and/or undershirts worn under your regular clothing are a great way to make even lighter pieces—from shirts to jeans to skirts and dresses—work in the depths of winter.

Here at Chatelaine, we’re big fans of Uniqlo’s Heattech, a line of thermal clothing in various weights, from regular to “ultra warm.” It’s inexpensive, durable, machine washable and great at retaining warmth without making you overheat. Verdict from our art department: “They just feel cozy.”

Below, some base layer inspiration in the form of Uniqlo’s bestselling Heattech pieces from their women’s line.

Soft, warm and breathable, this turtleneck is perfect for those chilly winter evenings—plus, it comes in nine different colours. For a more fitted turtleneck, several of our editors swear by the extra-warm turtleneck, which looks great both on its own and under a slip dress.
