Flannel shirts are typically made from a soft, woven fabric known as flannel, which is often brushed to create a warm, fuzzy texture. They are commonly made from cotton or a cotton blend, making them comfortable and breathable. Flannel shirts are popular for their versatility and are often worn in casual settings, especially during cooler weather. These shirts are characterized by their distinctive plaid or checkered patterns, although they can also come in solid colors. Originally associated with workwear and outdoor activities, flannel shirts have become a staple in many wardrobes, appealing to both men and women for their style and comfort.
