To use this tee, simply put it on and enjoy its comfort and style. When it comes to washing, it's best to follow the care instructions on the label. Since it's pre - shrunk, you won't have to worry too much about shrinkage at home. But keep in mind that there might be some shade variations due to the pigment dye process, which is normal. Store it in a cool, dry place to keep it in good condition. If you want to iron it, use a low - heat setting to avoid damaging the design.
