To wear these XENOS tank tops, just put them on like you would any other top. For men and those choosing the unisex style, pick your size from XS to 2XL. Women can choose from XS to 4XL. When it comes to washing, remember to use cold water and turn the tops inside out. Wash them with similar colors. Only use non - chlorine bleach if needed. After washing, hanging them to dry will give the best results, but you can also use a tumble dryer on a cool or low - heat setting. Don't use fabric softener as it might fade the color. And never iron or dry clean these tank tops to keep them in good condition.
