Using these 'Attack on Vader' tank tops is easy - just put them on and enjoy the comfort! When it's time to wash, remember to turn them inside out and wash in cold water with clothes of similar colors. If they get dirty, you can use non - chlorine bleach, but only when really needed. After washing, it's best to hang them to dry. If you're in a hurry, you can use the tumble dryer on a cool or low - heat setting. Be careful not to use fabric softener because it can make the colors fade. And never iron or dry clean these tank tops to keep them in good condition for a long time.
