This 'Shapechanger' long - sleeve t - shirt is a great addition to your wardrobe. You can wear it casually on any day. When it comes to washing, just put it in the washing machine on a cold setting, and turn it inside out to keep it looking good. Wash it with clothes of similar colors to avoid color bleeding. Only use non - chlorine bleach if there are stains. After washing, hanging it to dry will give the best result, but if you're in a hurry, you can use the tumble dryer on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. Also, don't iron or dry clean this shirt to keep its shape and material in top condition.
