The United States is the leading country in the fashion design industry, followed by France, Italy, the United Kingdom, Germany, and Japan. Apart from professional business attire, American fashion is eclectic and predominantly informal. While Americans' diverse cultural roots are reflected in their clothing, particularly those of recent immigrants, cowboy hats, boots, jeans, and leather motorcycle jackets are emblematic of specifically American styles.
New York City, and to a lesser extent Los Angeles, are the centers of America's fashion industry. They are considered leading fashion capitals. New York City is considered to be one of the "big four" global fashion capitals, along with Paris, Milan, and London. A study demonstrated that general proximity to Manhattan's Garment District was important to participate in the American fashion ecosystem.

History
French colonists in the Colonial United States wore European fashions from the land of their origin. The pilgrims of Plymouth colony adopted the new English fashion of King Charles I, the falling band collar made of lace or linen. Men's attire consisted of a linen undergarment, a padded button-down doublet with long sleeves, sometimes worn with cloth collars and white cuffs that contrasted with dark colored garments, baggy knee length breeches, and knee-length stockings of cotton or wool. Felt hats were worn at all times, even indoors. This was a standard set by the men at that time because, in those days, the men were extremely embarrassed of balding. Women wore a short-sleeved linen undergarment tied with ribbons, stays, ankle length petticoats (sometimes multiple layers), a fitted gown or fitted button down bodice (sleeves could be sewn on or attached at the shoulder with a ribbon) with an ankle length skirt, stockings, and aprons. Pilgrim women always wore their hair pulled back and covered with a cap called a coif.

Sumptuary laws in colonial Massachusetts forbade lace, embroidery, ruffs and gold thread in 1634. Perfumed gloves, decorative shoe ornaments, beaver fur hats, and multiple pearl necklaces and rings were also not allowed. Additional restrictions were added in 1639 requiring poorer colonists to dress according to their station, forbidding silk scarves and other finery. Loose hair and short sleeves were banned. During the Salem Witch Trials, Bridget Bishop was accused of witchcraft for her "showy costume". Her dress, black with a red bodice, and decorated with multi-colored threads, was admitted as evidence against her. Further evidence revealed that she had asked the town dyer to dye "sundry pieces of lace" that were said to be of "long and immodest shapes".

Fashion norms have changed greatly between decades. The United States of America has generally followed, and in some cases led, trends in the history of Western fashion. It has some unique regional clothing styles, such as western wear.
Blue jeans were popularized as work clothes in the 1850s by Levi Strauss, an American merchant of German origin in San Francisco, and were adopted by many American teenagers a century later. They are now widely worn on every continent by people of all ages and social classes. Along with mass-marketed informal wear in general, blue jeans are perhaps American culture's primary contribution to global fashion. Other fashion trends started in the US include sportswear as fashion along with athletic shoe wear like Converse or Nike. Athleisure was also popularized in the US in the 2010s, and has dominated the US market because of its ability to fill a gap in the market, as clothing was not usually both comfortable, stylish, and functional.
Fashion industry
The headquarters of many leading designer labels such as Ralph Lauren Corporation, Calvin Klein, J.Crew, Michael Kors, Alexander Wang, Vera Wang, Marc Jacobs, Oscar de la Renta, Diane von Furstenberg, Donna Karan, and Victoria's Secret, reside in Manhattan. Labels such as Abercrombie & Fitch and Eckō Unltd. cater to various niche markets, such as pre teens. A new trend in the United States towards sustainable clothing has led to the emergence of organic cotton T-shirts from labels such as BeGood Clothing. New York Fashion Week is also one of the most influential fashion weeks in the world, and occurs twice a year.
