To use these tank tops, simply put them on and enjoy the comfort. For sizing, check the size chart to pick the right fit. When it's time to clean, machine wash them cold inside out with similar colors. If they get dirty, you can use non - chlorine bleach but only when really necessary. After washing, it's best to hang them to dry. If you're in a hurry, you can tumble dry on cool or low heat. Just remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry clean these tank tops to keep them in good shape.
