Clothing is an important aspect of appearance.
There are dress codes on certain social occasions and for certain jobs. Schools may require school uniforms; if plain clothes are allowed there may be restrictions (see for example  (http://www.madison.k12.ky.us/mm/School%20Information/mms_dress_code.htm) ). A doorman or -woman of an entertainment facility such as a disco or nightclub[?] may judge visitor's clothing and refuse entrance in the case of disapproval.

Clothing production methods:
Some clothing is specialised equipment for a special purpose, such as a diving suit (these are included in the list below).
Some clothing materials are fetishized by some people, perhaps on the basis that the material forms a "second skin" that acts as a fetishistic surrogate for the wearer's own skin. The most common forms of this are spandex fetishism and rubber fetishism, in which the fabric is both stretchy and shiny, exaggerating some of the aspects of human skin. Another form is transvestic fetishism.
Part of the surface of clothes may be made retroreflective (small parts of coats, large parts of special high-visibility clothing for rescue workers etc.). This way they become much more visible in the dark for observers near a light source, such as the driver of a car with its headlights on. The pattern of the retroreflecting parts also helps to distinguish between objects and people.
For greater visibilty at daytime, as well as for decoration, very bright colors are obtained with fluorescence.
The opposite are clothes with a camouflage pattern.
