Generally, cotton shrinks when it is washed and/or dried. The least amount of shrinkage will be incurred if the t-shirt is washed in cold water and hung dry. The greatest amount of shrinkage occurs when the t-shirt is washed in hot water and dried on the hottest dryer setting. Usually, our 100% cotton t-shirts shrink approximately 3-5 percent in both the length and width after being washed.
