Fashion is a style or way of dressing, a distinct look that changes over time. It is a global industry and a highly visible form of self-expression. It is influenced by social factors, such as economic conditions and cultural values. It may also refer to a specific design, such as a hat or shoes. The fashion industry consists of designers, manufacturers, marketers and retailers. Designers create clothes and accessories that reflect current tastes and trends. They often research historical and cultural influences to inspire their work. They also use fabric, colour, and silhouette to convey meaning and emotion in their collections.

Fashion can be ephemeral, with designers expected to produce new styles every season, and consumers frequently updating their wardrobes. However, there are some styles that remain in fashion for longer periods of time. For example, the cinched waist of the 1950s or the long overcoats of the 1920s.

In addition to creating new trends, the fashion industry seeks to reinvent classic designs. This is accomplished by adjusting the materials, colours or silhouette of an existing garment to appeal to consumers with different preferences or values.

The United States has the largest and most multifaceted fashion industry of any country in the world. It is home to many prominent designers, including Calvin Klein, Ralph Lauren, Tommy Hilfiger and Vans. The city of New York hosts one of the four major fashion weeks in the world, with New York Fashion Week occurring twice a year in February and September.
