When you wear these women's t-shirts, just put them on like you would any regular shirt. For the best fit, choose the right size from S to 4XL for the regular t-shirts or S to 3XL for the premium ones. When it's time to clean them, remember to machine wash them cold and turn them inside out. Wash them with clothes of similar colors. Only use non - chlorine bleach if it's really necessary. After washing, hanging them to dry will give the best results, but you can also tumble dry on cool or low heat. Don't use fabric softener because it might make the colors fade. And please don't iron or dry clean these shirts to keep them in good condition.
