To use these Barrymore knit pants, simply put them on like you would any other pair of pants. They're great for lounging at home or running casual errands. When it comes to washing, use a gentle cycle in cold water to keep the fabric in good shape. Avoid using harsh detergents as they can damage the viscose - nylon blend. Hang them to dry instead of using a dryer to prevent shrinking. And don't forget to iron on a low - heat setting if needed.
