Using this T - shirt is super easy. Just slip it on and you're ready to go for a casual day out or a relaxed event during spring or summer. When it comes to washing, it's recommended to turn the T - shirt inside out and use a gentle cycle in the washing machine. This helps protect the striped pattern. Also, use mild detergent to avoid damaging the polyester fabric. Don't bleach it as it can fade the colors. After washing, air - dry it instead of using a dryer on high heat, as high heat might shrink the shirt. Keep it away from sharp objects to prevent snags. Before buying, always double - check the size chart because each item may have a different sizing standard.
