Using this vest is a breeze. Just zip it up and pair it with your favorite tops and bottoms. You can wear it over a t - shirt on a cool day or layer it under a coat in colder weather. When it comes to washing, it's best to follow the care instructions on the label. Usually, a gentle machine wash with cold water is recommended to keep the colors and pattern looking fresh. Avoid using harsh detergents as they may damage the fabric. After washing, hang it to dry to prevent shrinking. Check the size chart carefully before buying to ensure you get the perfect fit. And remember, different suppliers might have slightly different sizing, so take your time to choose the right size for you.
