These tank tops are super easy to wear. Just slip them on and you're good to go! For sizing, men and unisex options range from XS to 2XL, while women's sizes go from XS to 4XL. When it comes to washing, put them in the washing machine on a cold cycle and turn them inside out. Wash them with similar colors. Only use non - chlorine bleach if you really need to. After washing, it's best to hang them to dry. But if you're in a hurry, you can use the tumble dryer on a cool or low - heat setting. Don't use fabric softener because it might make the colors fade. And remember, don't iron or dry clean these tank tops. That way, they'll stay looking great for a long time.
