A sweatshirt is a soft, long-sleeved pullover typically made from cotton or fleece fabric, designed to provide warmth and comfort in casual settings. It usually features a round neckline, ribbed cuffs, and a relaxed fit that makes it ideal for layering or everyday wear. Known for its versatility, a sweatshirt can be styled with jeans, joggers, or layered under jackets for a comfortable yet stylish look.
