A model is a person with a role either to display commercial products or to serve as an artist's model or to pose for photography.

A fashion show is an event put on by a fashion designer to showcase their upcoming line of clothing and/or accessories during a fashion week. Fashion shows debut every season, particularly the spring/summer and fall/winter seasons. This is where designers seek to promote their new fashions. The four major fashion weeks in the world, collectively known as the "Big 4", in chronological order of their eponymous fashion weeks, are those held in New York City, London, Milan, and Paris. Berlin fashion week is also of global importance.
