As higher end customers seek something a little different from commodity knitwear, mass customisation is a growing phenomenon. One third of all garments produced in today’s international fashion industry are not sold to the full price, having to be marked down. This is the result of long lead times in the garment industry due to increasing numbers of retailers sourcing products from countries in the Far East where manufacturing costs are lower. Why not do as many other business sectors do, first sell the product to the customer and then start production? This concept is not new and in industries such as the car industry has been a reality for years. Wajima Kohsan Ltd opened in 1995 Factory Boutique Shima in Wakayama, Japan, and this article shows how this shop operates. This is an example of mass customisation in the fashion business of knitted garments.
