To use this tee, simply put it on and enjoy the comfort. It's great for everyday wear, casual outings, or just lounging at home. When it comes to washing, you can machine - wash it in cold water with like colors to keep it looking its best. Use a gentle cycle to avoid any damage to the design. Don't bleach it as it might affect the colors, especially the pigment dye ones. Tumble dry on low to prevent shrinkage. Hang it up or fold it neatly when not in use. Since it takes 7 - 10 business days to be made, be patient and wait for your unique tee to arrive. And remember, the shade variations in pigment dye colors are a natural part of the process, so embrace the uniqueness of your shirt.
