To use this hat, simply place it on your head and adjust it to fit comfortably. You can wear it at different angles for various looks. When you're out in the sun, it'll protect your face and eyes. As for care, you can machine - wash it in cold water on a gentle cycle. Avoid using harsh detergents as they might damage the cotton fabric. After washing, reshape the hat while it's still damp and let it air dry. Don't put it in the dryer as high heat can shrink the hat or ruin its shape. Also, store it in a cool, dry place when not in use to keep it in good condition.
