Humans have been ingenious in devising 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. Meanwhile, 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 consider 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 reasonable clothing due to poverty or affordability, or simply lack of inclination, is sometimes said to be scruffy, ragged, or shabby.
