Many of our shirts are preshrunk, and when washed in accordance with the product labeling they will not shrink.
Please refer to the specific shirt on our site for more details, as we do offer limited edition shirts made from unique materials from time to time.
Use a mild detergent, environmentally-friendly if possible, and wash our shirts individually the first few times.
After that you can wash your shirts in cold water with other clothes, but keep using a mild detergent.
If the listing isn't clear enough, ask us, and we'll look into it for you.
