Here's how to make the most of your 'The Mad Skellington' long sleeve t-shirt. First, when it comes to wearing, just slip it on like any regular t - shirt. It's suitable for casual outings or just lounging at home. When it's time to clean it, remember to turn it inside out and wash it in cold water with clothes of similar colors. Only use non - chlorine bleach if there are stains. After washing, you can either hang it to dry for the best look or use the cool/low heat setting in the dryer. Stay away from fabric softener because it can make the colors fade. And don't try to iron or dry clean it, as this might damage the fabric.
