When you get your Cosmo Fantasy men's t-shirts or premium t-shirts, you can start wearing them right away. They're super comfortable due to the removable tags. For washing, just put them in the washing machine on a cold cycle, turn them inside out and wash with similar colors. If they get dirty and need bleaching, use non - chlorine bleach. After washing, hanging them to dry is the best way to keep them in good shape, but you can also tumble dry on cool or low heat. Remember, don't use fabric softener as it might fade the colors. And never iron or dry clean these shirts to keep their quality intact.
