Overview
Sport is an important factor in the evolution of Western clothing, as many clothes have been simplified in order to be adapted to a sporting practice. This is particularly the case of the jacket. The sporting practice brought the notions of comfort and mixity to the garment. Mixity which is expressed as much in the wearing of pants in women as in the adoption of color by men.

Sport is also a motor of technical innovation in terms of textile or form since the garment is used in extreme contexts: movements, external conditions, friction, etc. High tech materials are thus developed, providing specific technical qualities, for example materials that allow the evaporation of perspiration.

Historical
At the end of the nineteenth century, the popularity of the bicycle increased the appearance of light clothing for men and skirt-pants, and trousers, in women. The golf brings the cardigan, the sea baths bring swimsuit, the riding breeds the jodhpurs pants, the tennis gives birth to the pleated skirt, the ski causes the anorak, etc.1.

Even today, board sports influence the volumes of clothing.

In the 1920s, some couturiers were particularly interested in the creation of sportswear: this is the case of Elsa Schiaparelli2 and Madeleine de Rauch3. For their part, creators like Coco Chanel and Jean Patou launch a relaxed fashion for the city1.

In the 1970s, the influence of sportswear exceeded the sphere of sports practice, sportswear that can have a sporty look, now called sportswear Daniel Hechter is a major French representative4.

Beyond their appearance and functionality, sportswear and sportswear can be "message carriers" today. For example, new designers offer "ethical" clothing, with a style and technical quality equivalent to, or even superior to, the market. That is to say, the manufacture of these garments meets environmental and social standards respectful of the people who produce them.
