Here's how to make the most of your Blue Doom long sleeve t - shirt. Wear it casually or dress it up a bit for a semi - formal look. When it comes to washing, always turn it inside out and wash it in cold water with similar colors. Only use non - chlorine bleach if there are stains. After washing, hanging it to dry will keep it in the best shape, but you can also use the cool or low - heat setting on your dryer. Don't use fabric softener as it might fade the color. And remember, don't iron it or take it to the dry cleaner. This way, your t - shirt will stay in great condition for a long time.
