Here's how to make the most of your Arinesart Twilight Classic long - sleeve t - shirt. First, when it's time to wear it, just slip it on like any regular t - shirt. It fits great in sizes from S to 4XL. When it gets dirty, pop it in the washing machine on a cold cycle, and turn it inside out to protect the color. Wash it with similar colors to prevent bleeding. Only use non - chlorine bleach if there are stubborn stains. After washing, you can either hang it to dry for the best results, or if you're in a hurry, tumble dry it on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry - clean this shirt, as it might damage the fabric. Follow these steps, and your t - shirt will look great for a long time.
