How to use: You can wear this jacket over a t - shirt or a thin top for an extra layer of warmth and style. It's great for outdoor activities like walking, jogging, or just casual outings. Just zip it up and adjust the hood as needed. Notice: Since it has a tight - cut fit, if you plan to wear bulky clothes underneath, make sure to size up. Also, be careful when using the zip to avoid getting the fabric caught. Maintenance: Machine wash this jacket in cold water on a gentle cycle. Avoid using harsh detergents as they can damage the fabric. Hang it to dry instead of putting it in the dryer to maintain its shape and the softness of the fabric.
