These tank tops are easy to wear. Just put them on like any other top. For men and unisex sizes, they'll fit you well from XS to 2XL. Women have a wider size range from XS to 4XL. When it's time to clean them, machine wash them cold and turn them inside out. Wash with clothes of the same color. Only use non - chlorine bleach if really needed. After washing, it's best to hang them dry. But you can also tumble dry on cool or low heat. Don't use fabric softener because it might make the colors fade. And remember, don't iron or dry clean these tank tops.
