Quantified shirts are a real one-size-size-fits-all version of a shirt, only one-size-fits-all. A one-size-fits-all version of a shirt is a separate version for each user based on quantitative data. This was previously possible only in a small tailor's shop, where many of the current customizations on the market were “set-code custom”, i. E., user-styles were applied to the existing fixed-size shirts and were impersonated as “custom-order” in a “set-code” product. Quantities have accumulated through 20 years of experience in production management, which has resulted in a customized shirt for one person under large-scale production conditions。
