To use this long sleeve t-shirt, simply put it on and enjoy its comfortable fit. You can wear it on casual days out or just at home. When it comes to washing, use a gentle cycle with cold water to keep the colors vibrant and prevent shrinkage. Avoid using harsh detergents. Hang it to dry instead of using a dryer to maintain its shape. Since it's made to order, please be patient during the 7 - 10 business day processing time. The shade variations are a natural part of the pigment dye process, so don't worry if your tee has a unique color tone.
