These indoor Halloween women's t-shirts are great for your spooky indoor celebrations. When you get them, just put them on and show off your style. For washing, 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 there are stains. After washing, it's best to hang them to dry. If you're in a hurry, you can tumble dry on cool or low heat. Don't use fabric softener because it might make the colors fade. And remember, don't iron them or take them to the dry cleaner. This way, your t - shirts will stay in good condition for a long time.
