These tank tops are easy to wear. Just put them on and feel the comfort. For the men's and unisex ones, you can choose from XS to 2XL. Women have a wider size range from XS to 4XL. When it comes to cleaning, remember to machine wash them cold and turn them inside out. Wash them with similar colors to avoid color bleeding. Only use non - chlorine bleach if really needed. Hanging them to dry is the best way, but if you're in a hurry, you can tumble dry on cool or low heat. Stay away from fabric softener as it might make the colors fade. And don't try to iron or dry clean these tank tops. That way, they'll stay in great shape for a long time.
