To use these hoodies, simply put them on and enjoy the comfort and style. When it comes to washing, always machine - wash them cold and turn them inside out. Wash with similar colors to avoid color bleeding. Only use non - chlorine bleach if necessary. After washing, you can hang them to dry for the best results, or if you're in a hurry, tumble dry on cool or low heat. Don't use fabric softener as it can make the colors fade. And remember, don't iron or dry - clean these hoodies to keep them in good condition.
