How is a natural indigo denim shirt dyed? An old craftsman announces the whole process and then soaks the shirt in a natural indigo dye tank, squeezes and rotates it, which maximizes the amount of indigo dye so that it can stick to the shirt and attract it sufficiently. This process is repeated several times so that there is no severe indigo discoloration when the product is ready for market. This is also a very critical step, because when the shirt is worn, there is a lot of discoloration at every turn, and the experience will be very poor for consumers. The final step is to set the shirt on the hangar and hang it to dry, which is the product that can eventually be sold. As for the pricing, the natural indigo overalls shirt in the picture is priced at as much as $250.
