Here's how to get the most out of your Street Dogs long - sleeve t - shirt. First, when you're ready to wear it, just put it on like any other shirt. It's designed to fit comfortably in sizes from S to 4XL. When it's time to clean your shirt, machine wash it cold. Make sure to turn it inside out and wash it with clothes of similar colors. If it gets dirty and needs a bit of a boost, use non - chlorine bleach. After washing, hanging it to dry is the best way to keep its shape and color. But if you're in a hurry, you can tumble dry it on a cool or low - heat setting. One thing to keep in mind is that using fabric softener can make the colors fade, so skip it. And never iron or dry clean this shirt, as it might damage the fabric.
