To use this t-shirt, simply put it on like any other shirt. It's great for casual outings, sports, or just lounging at home. When it comes to washing, use a gentle cycle with cold water to keep the colors vibrant and the fabric soft. You can tumble dry on low, but avoid high heat as it might cause some shrinkage, although the pre-shrinking process reduces this risk. Hang it to dry if you want to be extra careful. Since the pigment dye has natural shade variations, don't be surprised if there are slight differences between your shirt and others. Also, remember that it takes 7 - 10 business days to process your order, so plan ahead.
