Okay kiddo, so a leg warmer is like a special sock that you wear on your legs. It looks kind of like a long tube that you pull up over your calf and up to your knee or even your thigh, depending on how long it is.
Sometimes people wear leg warmers when they exercise or dance to help keep their legs warm and flexible. And sometimes, people just wear them as a fashion accessory to look cool.
Leg warmers are usually made of stretchy materials like cotton, wool or acrylic, so they can fit snugly on your legs and stay in place while you move around.
There are lots of different colors and patterns of leg warmers to choose from, so you can pick ones that match your outfit or your personality. And they are super easy to put on and take off whenever you want!
