Marlow White- Helping our nation's best look their best since 1879. The Hidden Tailor is a rubberized belt that is worn over the shirttail but inside the trousers, just below the waistband. Because of the flexible rubber design of the belt, it will keep your shirt perfectly tucked in and also hold your trousers up - all through the day. When putting the Hidden Tailor on, make sure you stretch it an extra inch or so before fastening the quick-attach button. The elasticized belt will then be in place all through the day. The belt is designed to fit all waist sizes up to 48 inches. It is designed to be trimmed to fit the individual wearer.
