The most obvious function of clothing is to protect the wearer from the elements. It serves to prevent wind damage and provides protection from sunburn. In the cold, it offers thermal insulation. Shelter can reduce the functional need for clothing. For example, coats, hats, gloves, and other outer layers are normally removed when entering a warm place. Similarly, clothing has seasonal and regional aspects so that thinner materials and fewer layers of clothing generally are worn in warmer regions and seasons than in colder ones. Boots, hats, jackets, ponchos, and coats designed to protect from rain and snow are specialized clothing items.
Clothing has been made from a wide variety of materials, ranging from leather and furs to woven fabrics to elaborate and exotic natural and synthetic fabrics. Not all body coverings are regarded as clothing. Articles carried rather than worn normally are considered accessories rather than clothing (such as Handbags), items worn on a single part of the body and easily removed (scarves), worn purely for adornment (jewelry), or items that do not serve a protective function. For instance, corrective eyeglasses, Arctic goggles, and sunglasses would not be considered an accessory because of their protective functions.
Clothing protects against many things that might injure or irritate the naked human body, including rain, snow, wind, and other weather, as well as from the sun. Garments that are too sheer, thin, small, or tight offer less protection. Appropriate clothes can also reduce risk during activities such as work or sport. Some clothing protects from specific hazards, such as insects, toxic chemicals, weather, weapons, and contact with abrasive substances.
Humans have devised clothing solutions to environmental or other hazards: such as space suits, air conditioned clothing, armor, diving suits, swimsuits, bee-keeper gear, motorcycle leathers, high-visibility clothing, and other pieces of protective clothing. The distinction between clothing and protective equipment is not always clear-cut since clothes designed to be fashionable often have protective value, and clothes designed for function often incorporate fashion in their design. The choice of clothes also has social implications. They cover parts of the body that social norms require to be covered, act as a form of adornment, and serve other social purposes. Someone who lacks the means to procure appropriate clothing due to poverty or affordability, or lack of inclination, sometimes is said to be worn, ragged, or shabby.
Clothing performs a range of social and cultural functions, such as individual, occupational and gender differentiation, and social status. In many societies, norms about clothing reflect standards of modesty, religion, gender, and social status. Clothing may also function as adornment and an expression of personal taste or style.
