To use this tee, simply put it on and enjoy the comfort! When washing, use a gentle cycle with cold water to keep the colors and fabric in good condition. Avoid using bleach as it can damage the low-impact dyes. Hang it to dry or tumble dry on low to prevent shrinking. The pre-shrunk feature means it won't shrink much, but it's still better to be cautious. The pigment dye colors give it a vintage look that will stay with you as long as you own the tee. Just be aware that there might be some shade variations, which are normal for this dyeing process. Overall, this is a great, comfortable tee that you can wear for many occasions.
