A pullover is a type of garment, typically made of fabric, that is worn over the head and covers the upper body. It is designed to be pulled on and off easily, without the need for buttons or zippers. Pullovers often have long sleeves and a close-fitting neckline, such as a crew neck or a V-neck. They are commonly used as a casual or informal piece of clothing and are available in various styles, colors, and materials.
