Using this shirt is super easy. Just slip it on over your head and fasten the single - breasted closure. You can wear it on its own for a casual look or layer it over a t - shirt for added style. When it comes to washing, it's best to turn the shirt inside out and use a gentle cycle with cold water. Avoid using harsh detergents as they can damage the fabric. After washing, reshape the shirt while it's still damp and let it air dry. Don't wring it out to prevent any stretching. Iron it on a low - heat setting if needed, especially around the collar and sleeves to keep them looking sharp. Always check the specific size chart for this item to ensure you're getting the right fit.
