Most people are familiar with the word jersey, whether a sports uniform or a pullover knit sweater comes to mind. But it's also often used to describe one of the comfiest types of cotton fabric. Jersey cotton is a type of knitted fabric known for its soft, comfy feel and laid-back aesthetic. The textile is also notably stretchy. While traditional cotton doesn't have this flexibility, the knitting technique gives it an elastic quality, even without blending synthetic fibers like elastane or spandex.
