Suspenders are a clothing accessory designed to hold up a pair of pants or trousers. They consist of a set of straps which go over the shoulders and attach to the pants with buttons or clips. The pants are literally suspended from these straps, which explains the origin of the name. In British English, they are known as braces, because they could be said to brace, or support, a pair of trousers. While suspenders are no longer widely worn, they are available from gentlemen's supply stores and other specialized clothing stores, depending on the desired style.

On the front of the body, the straps of a pair of suspenders travel straight down from the shoulders, to attach to the pants with clips or to be buttoned in, depending on the design of the pants. In the back, the suspenders are often crossed, to provide more stability and prevent them from sliding off the shoulders. Sometimes, a y-shape is made, by connecting the straps together to form a single strap which attaches in the middle of the back of the pants. Either way, the suspenders are elasticized and typically include buckles so that they can be adjusted to fit the wearer.

Modern suspenders are usually fully elasticized. More formal suspenders may be made from stiffer materials with elasticized tabs for some flexibility of movement. In addition to elastics, suspenders can be made from rugged cotton material and leather in an assortment of colors. They come in different base lengths to accommodate a wide range of bodies, from short men to very tall ones. Some companies also make joke suspenders, imprinted with bright and funny patterns.

Suspenders were popular throughout the 1800s, and were worn by all men. Belts were used ornamentally, on the outside of clothing and coats, while suspenders did the work of holding pants up. These traditional suspenders were designed to hook into buttons attached to the pants. This changed in 1894, when David Roth filed a patent for clasping suspenders, rather than suspenders which buttoned directly into pants.

Suspenders waxed and waned in popularity during the twentieth century. Modern suspenders usually fall into two categories: highly formal dress suspenders, designed to be buttoned into pants as part of a white tie outfit, or basic working suspenders used by farmers, plumbers, and carpenters. These suspenders prevent the workman's pants from falling, even with laden pockets and a full tool belt.
