Using these Studio Yumie hoodies is easy. Just put them on and enjoy their comfort. When it's time to clean, remember to machine wash them cold and turn them inside out. Wash with like colors to prevent color bleeding. Only use non - chlorine bleach if really necessary. After washing, hanging them to dry will give the best results, but you can also use a tumble dryer on a cool or low - heat setting. Avoid using fabric softener as it can make the colors fade. And don't try to iron or dry clean these hoodies to keep them in good condition.
