To use this tee, simply put it on and enjoy its comfort all day long. When it comes to washing, use a gentle cycle with cold water to keep its colors and shape. Avoid using harsh detergents as they might damage the fabric or the design. Hang it to dry to prevent shrinkage, especially if it's made with pigment dye. If you need to iron it, use a low - heat setting. And remember, since these tees are made to order, it takes 7 - 10 business days to process, so plan ahead.
