Itaewon is close to the where all the foreign dignitaries live in the UN Village. To dress these diplomats and foreign businessmen, Itaewon has come to be known as the place to get custom made shirts and suits in Seoul. And out of all the tailors here, Hamilton Shirts have become the most famous of all the custom suit shops. Here you’ll find veteran tailors who’ll take your measurements and create suits or shirts with the fabrics of your choice. They have several locations throughout the city, and they keep a database of your sizes so you can have more suits and shirts made without having to visit the same store (they’ll even ship overseas).
