- "INDIVIDUALIZED SHIRTS" was established in 1961 in Amboy, New Jersey. It is a talented factory that boasts the No. 1 share in the field of custom-made shirts in the United States. Speaking of American button-down shirts, the historic Brooks Brothers company, which was founded in 1818, is world-famous, and "INDIVIDUALIZED SHIRTS" had received high praise and tremendous trust from Brooks Brothers company and got orders from them for the custom-made line of the shirt for about 40 years. Even now that has passed more than 50 years since then, "INDIVIDUALIZED SHIRTS" continues to produce high-quality shirts with full use of the latest technology while inheriting the old-fashioned manufacturing method.
