To use this tee, simply put it on and enjoy its comfort. When it comes to washing, you can machine - wash it in cold water to keep the colors vivid and prevent shrinkage. Don't use bleach as it may damage the fabric and the dyes. Hang it to dry or tumble dry on low heat. Store it in a cool, dry place. Remember, the tees are made to order, so allow 7 - 10 business days for processing. And be aware that there may be shade variations due to the pigment dye process, which is completely normal.
