Using these women's t-shirts is as easy as putting them on! Just pick the right size from S to 4XL for regular t-shirts or S to 3XL for premium ones. When it's time to clean them, machine wash them cold, inside out with similar colors. Only use non - chlorine bleach if necessary. After washing, you can hang them to dry for the best results, or tumble dry on cool/low heat. Be careful not to use fabric softener because it can make the colors fade. Also, don't iron or dry clean these shirts to keep them in good condition.
