Traditional manufacturing processes usually depend solely on skilled manpower. This is normal slow and production is low. However, depending on the skill of the workers and quality of materials they are able to produce high quality products. Roll Royce is an example of what is, at least partially, handmade. Leather items like Louis Vuitton handbags, and shoes, like UGG boots, are usually still handmade. However, because of the toughness of leather, sewing machines are used to aid the worker and increase production. Often, complexity of the product prevents from being made solely by machines. Also, some handmade workmanship cannot be replicated by automation. Ethnic products, like some fabrics and rugs, are still traditionally made by hand and as such are highly prized.
Automation increases product quantity. This increases available supply which, in turn, lowers cost and, consequently, selling price. Cloth, like denim in which True Religion jeans are made from, are almost always manufactured with automation.
