Clothing refers to any covering for the human body. The wearing of clothing is exclusively a human characteristic and is a feature of most human societies. The amount and type of clothing worn depends on functional considerations (such as a need for warmth or protection from the elements) and social considerations. In some situations the minimum amount of clothing (i.e. covering of a person's genitals) may be socially acceptable, while in others much more clothing is expected.

Functionality is the primary purpose of clothing. It can serve as protection from the elements. Clothes also enhance safety during hazardous activities such as hiking and cooking, by providing a barrier between the skin and the environment. Further, clothes provide a hygienic barrier, keeping toxins away from the body and limiting the transmission of germs.
