A handkerchief /ˈhæŋkərtʃɪf/, also called a hanky or historically handkercher, is a form of a kerchief, typically a hemmed square of thin fabric that can be carried in the pocket or purse, and which is intended for personal hygiene purposes such as wiping one's hands or face, or blowing one's nose. A handkerchief is also sometimes used as a purely decorative accessory in a suit pocket, it is then called a pocket square. It is also an important accessory in many folkdances in many regions like the Balkans and the Middle East; an example of a folkdance using handkerchiefs is Kalamatianos.
The material of a handkerchief can be symbolic of the socioeconomic class of the user, not only because some materials are more expensive, but because some materials are more absorbent and practical for those who use a handkerchief for more than style. Handkerchiefs can be made of cotton, cotton-synthetic blend, synthetic fabric, silk, or linen.
Handkerchiefs were also used, especially by children, as an impromptu way to carry around small items when a bag or basket was unavailable. They could also serve as a substitute for a bandage over a small injury. In the United Kingdom, the habit of wearing a handkerchief with tied corners on one's head at the beach has become a seaside postcard stereotype, referenced by the Gumby characters in Monty Python's Flying Circus.
