To use this vest, simply unzip it and put it on over your top. You can zip it up to keep warm or leave it partially open for a more casual look. You can put your phone, keys or other small items in the pockets. When it comes to care, always remember to machine wash it in cold water and tumble dry on low to keep the material in good condition. Since it's imported, follow these care instructions carefully to ensure its longevity. Don't use hot water or high - heat drying as it may damage the 100% polyurethane material. Also, check the size chart before buying to make sure you get the right fit for your bust and waist measurements.
