More than a third of women’s clothes, with a median price of $40,000, were produced in the US in 2014, according to a report published in the journal New Scientist.
The most expensive item was a dress by designer Diane von Furstenberg for $10,000.
The study, conducted by a group of researchers from New York University, the Smithsonian Institution and the International Business Machines Corporation, examined fashion trends in the United States from 2001 to 2014.
Many of the items in the study were more expensive than what the average American bought for their first garment, the researchers found.
Some of the trends they examined were: more conservative clothing styles for women with shorter legs, lower waists and shorter tops, as well as for younger women, those aged 30 to 44 and those who are overweight.
Among the other trends examined, the study found that men’s clothes were more conservative.
Men were less likely to buy clothing made of high-quality materials and more likely to wear plain fabrics such as cotton, polyester and wool.
The study also found that women’s and men’s clothing were more alike in styles, colours and patterns.
Women’s clothing was more likely than men’s to have a waist-length skirt, while men were more likely in both genders to wear shirts with shoulder pads.
Men also wore trousers, while women wore skirts.
In terms of style, men’s dress was more conservative than women’s, and women’s was more liberal, according the study.
Although most of the clothing was made of a material known as merino, the authors found that merino was used in more than one-third of the garments produced.
Merino fabrics were made from sheep wool and were not considered a fashion item in the U.S., according to the researchers.
