Clothes are visible and meaningful. They have a semiotic dimension: both messages and message carriers. Clothes are often used to highlight the wearer, they are sometimes a sign of social class, function (uniform police, firefighter, army).

They can also be a factor of integration in a group. This is particularly the case for teenagers, who are very influenced by fashion and commercial brands. Some professional clothing is said to "high visibility" (fluorescent yellow or orange color, reflective strips) so that drivers of construction equipment and vehicles on the road can see them better, and thus avoid accidents. On the other hand, other clothes have the role of camouflage, making it difficult to see the person in the environment, such as the infantrymen's battle dress.

The shape and color of clothes are often a strong symbol. Thus, in Europe, women have long worn only dresses and skirts, that is to say clothes leaving symbolically "free access" to their sex. Moreover, the ordinance of the police prefecture of Paris prohibiting women in 1800 to dress as a man (and the reverse order promulgated in 1907 by Louis Lépine, forbidding men to disguise themselves as a woman) has not was repealed in February 2013. In Europe, black is the color of mourning and white is that of purity, virginity, therefore the color of marriage. On the other hand, in Asia, white is the color of mourning.

In Muslim culture, there is no difference between the liturgical dress and the holding of daily life. In Islam, the religious life and the secular life are much more intertwined, one passes constantly from one to the other without any transition other than the ablutions. Indeed, the essential function of the garment of daily life is to allow and facilitate the fulfillment of prayer

The fibers used for clothing design fall into two categories: natural fibers and synthetic fibers. Cotton is the most used natural fiber in the textile industry. It gives clothes a thermal insulation and a power of absorption of perspiration. there are other natural fibers such as abaca, hemp, coconut fiber, jute, wool, linen, sisal, silk, mohair, ramie, etc ...

The use of natural fiber such as cotton in an industrial manner, that is to say the use of automatic weaving machine, requires that it be of good quality. In the case of reduced quality the use of synthetic fibers is necessary. This also has the effect of reducing the cost of production.

Synthetic fibers have emerged on the market since the 2000s. One of the main fibers used is polyester other than cost, it confers new properties to the garment. It is mainly used in technical clothing. Synthetic fibers are made from a non-renewable resource and very difficult to recycle, releasing large amounts of micro-plastic into the environment.
