These tank tops are super easy to wear. Just slip them on and you're good to go. For sizing, men and unisex styles range from XS to 2XL, and women's styles are from XS to 4XL. When it's time to clean them, put them in the washing machine on a cold setting, turn them inside out and wash 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 the tumble dry function on a cool or low - heat setting. Remember, don't use fabric softener as it might make the colors fade. Also, avoid ironing and dry cleaning these tops to keep them in good shape.
