Suspenders or braces (English English) are fabric or leather straps worn over the shoulders to hold up trousers. Straps may be elasticized, either entirely or only at attachment ends and most straps are of woven cloth forming an X or Y shape at the back.
The modern type was first invented in 1822 by Albert Thurston and were once almost universally worn due to the high cut of mid-nineteenth and early twentieth century trousers, a cut that made a belt impractical. After losing popularity in the first World War, as men became accustomed to uniform belts, braces were still standard throughout the 1920s. While they have been in and out of fashion over the last century ,they are becoming popular again in 2008 in America and Britain following the resurgence of styles seen in period dramas such as the 2008 re-make of Brideshead Revisited.
