These tank tops are super easy to wear. Just slip them on and you're good to go! For sizes, the men's and unisex ones are available from XS to 2XL, and the women's are from XS to 4XL, so you can pick the perfect fit. When it comes to cleaning, machine wash them cold, turning them inside out and washing with like colors. Only use non - chlorine bleach if needed. After washing, hanging them to dry gives the best results, but you can also tumble dry on cool or low heat. Don't use fabric softener because it might make the colors fade. And remember, don't iron or dry clean these tank tops to keep them in good condition.
