To use this Summerween long - sleeve crewneck t - shirt, simply put it on and enjoy its comfort all day. When it's time to clean, toss it in the washing machine on a cold cycle, and make sure to turn it inside out and wash with similar colors. Only use non - chlorine bleach if really needed. After washing, you can either hang it to dry for the best results or use the cool/low heat setting in the dryer. Don't use fabric softener because it might make the colors fade. And remember, don't iron or dry clean the shirt to keep it in great condition.
