How to use these Halloween-themed women's t-shirts is simple - just put them on and show off your style! When it comes to washing, remember to turn them inside out and wash in cold water with similar colors. Only use non - chlorine bleach if needed. After washing, hanging them to dry is the best option, but you can also use a tumble dryer on cool or low heat. Avoid using fabric softener as it can make the colors fade. And don't try to iron or dry clean these shirts to keep them in good condition for a long time.
