Thus, as men wore vests less in the 1930's, they also wore suspenders less. Up until the mid-twentieth century suspenders were still considered an undergarment, and were covered by vests, waistcoats, or cardigans. Suspenders lost some popularity following World War I, where men had become used to wearing belts with their uniforms. Samuel Clemens, better known by his pen name, Mark Twain, received an early patent for suspenders in 1871. In the late nineteenth and early twentieth centuries they were almost universally worn, because most people wore high cuts pants, which made belts impractical. Modern day suspenders were invented in 1820 by Albert Thurston, and their popularity has waxed and waned since then. Outside the United States the term suspenders refers to a garter belt. In Britain they are known as braces, and in the nineteenth century they were sometimes called galluses.
Suspenders usually form an X or Y shape on the wearer's back, and attach with clips or buttons. Today is devoted to suspenders, an accessory made of straps of fabric or leather that cross over a wearer's shoulders and hold up their pants.
