To use this tee, simply put it on and enjoy its comfort! When it comes to washing, you can follow normal laundry procedures. But since it's pre-shrunk, you don't have to worry too much about shrinkage at home. For the pigment dye colors, keep in mind that the shade variations are normal and part of its unique vintage look. Store it in a cool, dry place. If you have any questions, feel free to reach out to our customer service.
