To use this tee, simply put it on and enjoy the comfort and unique 3D design. When it comes to washing, follow the care instructions on the label. Since it's made with pre-shrunk fabric, you don't have to worry too much about shrinkage at home. The pigment dye colors give a vintage look but may have some shade variations, which is normal. Avoid using harsh chemicals or bleach as it may damage the fabric and the design. Hang it to dry to keep its shape. This tee is sustainably made, so take good care of it and it'll last you a long time.
