These Blue Shell tank tops are easy to wear. Just put them on and enjoy the comfort. For men and unisex sizes, you can choose from XS to 2XL. Women have a wider range from XS to 4XL. When it comes to washing, use cold water and turn the tops inside out. Wash them with clothes of 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. Remember, fabric softener can make the colors fade, so don't use it. Also, avoid ironing and dry - cleaning these tank tops to keep them in good condition.
