How to use: Slip on this '7 Diamonds' button - down shirt for any event, whether it's a casual day out or a semi - formal gathering. Just button it up and adjust the cuffs to your liking. Note: Avoid using hot water or high - heat settings when washing and drying, as it may damage the fabric's stretch and shape. Maintenance: Machine wash it in cold water. After washing, hang it to dry instead of putting it in the dryer. This will help maintain its wrinkle - resistant and moisture - wicking properties, and keep the shirt looking great for a long time.
