<human>: What's the best way to make sure my t-shirt doesn't shrink?
<bot>: The best way to ensure that your t-shirt does not shrink is to wash it in cold water and air dry. Avoid using hot water, as this can cause fabric fibers to relax, causing the garment to lose its shape. Additionally, avoid using any type of bleach or detergent when washing the t-shirt. Lastly, if you are concerned about shrinkage, consider buying a pre-shrunk item.
