A necktie, or simply a tie, is a piece of cloth worn for decorative purposes around the neck, resting under the shirt collar and knotted at the throat, and often draped down the chest.
Variants include the ascot, bow, bolo, zipper tie, cravat, and knit. The modern necktie, ascot, and bow tie are descended from the cravat. Neckties are generally unsized but may be available in a longer size. In some cultures, men and boys wear neckties as part of office attire or formal wear. Women wear them less often. Neckties can also be part of a uniform. Neckties are traditionally worn with the top shirt button fastened, and the tie knot resting between the collar points.
The bow tie /boʊ/ is a type of necktie. A modern bow tie is tied using a common shoelace knot, which is also called the bow knot for that reason. It consists of a ribbon of fabric tied around the collar of a shirt in a symmetrical manner, so that the two opposite ends form loops.
There are generally three types of bow ties: the pre-tied, the clip on, and the self tie. Pre-tied bow ties are ties in which the distinctive bow is sewn onto a band that goes around the neck and clips to secure. Some "clip-ons" dispense with the band altogether, instead clipping straight to the collar. The traditional bow tie, consisting of a strip of cloth which the wearer has to tie by hand, is also known as a "self-tie", "tie-it-yourself", or "freestyle" bow tie.
Bow ties may be made of any fabric material, but most are made from silk, polyester, cotton, or a mixture of fabrics. Some fabrics (e.g., wool or velvet) are much less common for bow ties than for ordinary four-in-hand neckties.
