A fashion show is an event put on by a fashion designer to showcase their upcoming line of clothing and/or accessories during Fashion Week.

Even though they are often used together, the term fashion differs from clothes and costume, where the first describes the material and technical garment, whereas the second has been relegated to special senses like fancy-dress or masquerade wear. Fashion instead describes the social and temporal system that "activates" dress as a social signifier in a certain time and context.
