Fashion is a hard word to describe, but it generally refers to clothing and clothing trends. When people think about fashion, they generally think about high fashion – items of clothing that are unique, trend setting, and not readily available. High fashion clothing can often be seen on the red carpet being worn by celebrities. Custom, one-of-a-kind high fashion garments are referred to as haute couture. To be couture, a fashion house must be a member of the Syndical Chamber of Haute Couture of Paris, an honour that only 16 fashion houses currently have. Yet high fashion is not the only aspect of fashion. Fashion includes all aspects and styles of clothing, although it is usually used when referring to items that are trendy or popular with a large group of people. Affordable pieces(or individual items of clothing) that are worn by a large number of people are referred to as street-style, or street-fashion. Any garments purchased in a store or online (that are not custom-made), are known as ready-to-wear fashion.
