To use these women's t-shirts, simply put them on and enjoy the comfort. When it's time to clean, machine wash them in cold water, turning them inside out and washing with similar colors. Only use non - chlorine bleach if necessary. After washing, you can hang them to dry for the best results, or use the cool/low heat setting in the dryer. Don't add fabric softener as it can make the colors fade. Also, stay away from ironing and dry - cleaning to keep the shirts in good condition.
