These tank tops are easy to wear. Just put them on and enjoy the comfort. For men and unisex ones, they fit well in regular sizes from XS to 2XL. Women can choose from sizes XS to 4XL. When it comes to cleaning, always machine wash them cold and turn them inside out. Wash with clothes of similar colors to avoid color transfer. Only use non - chlorine bleach if necessary. After washing, it's best to hang them to dry. But if you're in a hurry, you can tumble dry with cool or low heat. Don't use fabric softener as it might make the colors fade. And remember, no ironing and no dry cleaning to keep them in good shape.
