<bot>: The best type of clothing to wear in the winter when it is cold outside is layers. Layering allows you to add or subtract clothing as needed depending on the temperature and your comfort level. A good base layer, such as a long-sleeved shirt, helps keep your body warm while allowing your skin to breathe. A mid-layer, such as a sweater or jacket, provides additional warmth and protection from the elements. Finally, outerwear such as a coat or parka will help protect against wind and precipitation.
