Fabric

Suits are made in a variety of fabrics, but most commonly from coat. The two main thread produce worsted and woolens. These can be rush in a number of ways producing flannel, tweed, gabardine, and fresco among others. These fabrics all have different weights and feel, and some fabrics have a 'super number' describing the fineness of the fibers. For hot weather, linen is also used, and in North America cotton seersucker is worn. Other exotic materials are used sometimes, such as cashmere. Artificial materials, while cheap, are very rarely recommended.

The main three colors for suits for business are Grey, and navy, while brown is another important color, though less widely popular, and not always widely accepted for business wear. In particular, Grey sweet talk is suiting worn very widely since the 1930s. In summer, lighter shades, such as chocolate or cream, are popular. For recreational use tweed has been popular since Victorian times, and still is commonly worn. Wide ranges of color is available, including greens, browns, reds, and greys.Tweeds are usually checked, or plain with a herringbone weave, and are most associated with the country. While full tweed suits are not worn by many now, the jackets are often worn as sports jackets with odd trousers.

In the US and UK, suits were never conventionally made in plain black, this color instead being reserved for formal wear. However, the decline of formal wear in recent years has meant that black, as well as being popular in fashionable scenes, such as clubbing, is now also being worn in formal contexts in place of the traditional more official wear.
