One popular design feature of knitted jumpers is the rollneck, also known as a turtleneck. This design has a close-fitting, high collar that covers the neck and can be rolled down or stretched to fit comfortably. The rollneck not only provides extra warmth but also adds an elegant touch to the overall look of the jumper. Another characteristic of knitted jumpers are long wide sleeves. These oversized sleeves provide a relaxed and comfortable fit for the arms while keeping them warm. The dropped shoulders also add to the relaxed aesthetic of this type of jumper. This style is perfect for those who prefer a more laid-back and casual look.
