Fashion is a popular style, especially in clothing, footwear, lifestyle, accessories, makeup, hairstyle and body. Fashion is a distinctive and often constant trend in the style in which people present themselves. A fashion can become the prevailing style in behavior or manifest the newest creations of designers, technologists, engineers, and design managers. Because the more technical term costume is regularly linked to the term "fashion", the use of the former has been relegated to special senses like fancy-dress or masquerade wear, while the word "fashion" often refers to clothing, including the study of clothing. Although aspects of fashion can be feminine or masculine, some trends are androgynous.
