A brief history of denim – and why the ‘perfect pair’ of jeans remains elusive

Rose Marroncelli, Nottingham Trent University

Denim is present in practically every country in the world and is widely adopted as one of the most common forms of everyday attire. Its appeal spans generations and social groups: jeans are worn worldwide by those who follow fashion and those who do not, by people seeking to stand out and by those who prefer to blend in. However, many of us have never found the perfect pair.

Although denim has been produced since the 16th century, its association with American culture and durable workwear emerged during the Californian gold rush of the 1850s. It was during this time that Levi’s – now arguably the most recognisable denim brand – was established.

Levi Strauss, an immigrant entrepreneur who arrived in California from Bavaria in the 1850s, opened a dry goods business catering to miners. One of his customers, the tailor Jacob Davis, developed the innovative use of metal rivets to reinforce stress points in work trousers, making them more durable. Strauss and Davis jointly patented this technique, and the Levi’s brand was born.

Blue jeans were originally a seen as symbol of labourers (like the miners) and they also gained a strong association with cowboys. In the decades that followed, denim jeans evolved from practical workwear into one of the most iconic and enduring symbols of global fashion and culture. Film stars such as Marlon Brando and James Dean popularised the jeans and t-shirt look to a young generation in the 1950s. These films personified motorcycle-loving nonconformists, and 1950s Hollywood embraced denim as the garment of rebellion.

Today, the cultural significance of denim jeans has moved beyond early associations with workwear, the cowboy and the teenage rebel, to become a staple worn by people of all ages and backgrounds.

Finding the perfect pair

Denim jeans are often seen as a problematic fashion product in terms of sustainability, because their production leaves a considerable environmental footprint.

Cheap prices on the high street can encourage consumers to treat denim products as short-term items, reducing their lifespan. Cotton, which is commonly the main fabric for denim, is incredibly water intensive; the production of one pair of jeans uses approximately 7,500 litres of water.

Different components involved in the making of a single pair of jeans, such as denim, thread, cotton and buttons, can originate from different countries all over the world. This raises questions regarding the environmental costs involved in the production process. Further issues include that jeans are often not made from single fibre materials and therefore cannot be recycled.

Adding to sustainability concerns, at the consumer level, the perfect pair of jeans remains an elusive concept. But in a recently published book chapter, I explain that the perfect pair of jeans is elusive for a reason. Jeans have to be correct for the individual wearer in terms of comfort, social and personal identity, and also the complexity of fit.

Previous reports have focused on women’s struggle to find jeans that fit and are flattering. The inability to find the perfect pair of jeans may encourage overconsumption, due to repeated purchasing based on poor fit.

My research shows that this is an issue which applies to all genders. The men I spoke to noted how they resented paying a higher price for brands like Levi’s, so spent less by purchasing cheap, high street alternatives. This attitude can lead to overconsumption, as low price points achieved through low-quality production often compromise product longevity.

This demonstrates the perpetuating cycle of fast fashion, driven by cheap, low-quality production, and contradicts the original purpose of jeans of being highly durable and having longevity. The combination of highly environmentally damaging production processes with overconsumption results in even greater environmental harm.

Retailers can make efforts to reduce the trend of overconsumption with better fitting garments. However, fit is a complex issue for retailers as well as consumers. For the retailer, producing jeans in a wide range of sizes and styles is often not cost effective, and complex sizing systems can also confuse the consumer.

Technology could provide future solutions to improving the accuracy of fit. Personalised virtual fitting, made possible through improvements in 3D human shape recognition, could ensure improved fit for the consumer. This would benefit online shoppers, although the technology does remain in its infancy, and is yet to be adopted by major online fashion retailers. Virtual fitting rooms also cannot replicate the feeling of denim next to the skin, so although the fit may be perfect, comfort could be compromised.

Ultimately, the enduring challenge of finding the “perfect pair” of jeans highlights not only the garment’s cultural significance but also the opportunity for the fashion industry – and consumers – to move toward more sustainable, better-fitting and more thoughtfully designed denim for the future.The Conversation

Linen or cotton: Which fabric keeps you cooler in sticky summer heat?

A white cotton T-shirt and a linen button-down are both classic summer looks. But which of these fabrics will keep you cooler on a hot, humid day?

We spoke to three textile scientists who study fabrics and fibers on a molecular level to get a definitive, scientific answer about the most comfortable clothing material for hanging out on a summer afternoon. Their unanimous verdict: Linen will keep you cooler.

All three scientists agreed that if you’re working or exercising in the sun, you’d be better off in synthetic fabrics such as polyester that have been chemically treated to wick sweat away from your skin as fast as possible. But if athletic wear isn’t an option, linen offers the best combination of moisture removal and airflow.

“Linen is much better in terms of providing comfort,” said Sundaresan Jayaraman, a professor of material science and engineering at the Georgia Institute of Technology. “People worry about perfect storms. Linen is what I would call a positive storm because everything is nicely coming together.”

Moisture

When it’s hot out, your body’s main tool for cooling itself down is sweating. As sweat evaporates from your skin, it carries away heat. So in the summer, it’s important to wear a fabric that helps your body get rid of moisture.

“Your comfort is determined by how much body moisture is being released,” said Yiqi Yang, a professor of textile science at the University of Nebraska at Lincoln.

You want a fabric that’s absorbent enough to pull moisture away from your skin, but also allows the water to evaporate into the air. Cotton and linen are both very absorbent – but cotton retains water while linen lets it go, according to Jayaraman.

“If you happen to be walking on a hot, humid day wearing a cotton undershirt, by the time you get home, the undershirt is completely wet because it is capturing all the sweat from you, but it does not have the ability to transport the moisture vapor from your garment to the outside world,” he said. “That’s why you feel clammy.”

You can see why cotton and linen behave differently when you put their fibers under a microscope, said Larissa Marie Shepherd, an assistant professor of fiber science at Cornell University. Cotton fibers, which come from the fuzzy bolls that swaddle cotton seeds, look like ribbon and tend to be full of kinks, twists and bends. Linen fibers, which come from the stems of long, tall flax stalks, look more like bamboo rods and tend to be straighter and stiffer.

“The ribbon shape of cotton can trap water more,” Shepherd said. “Flax is straight, so there’s not as many places for the water to be trapped inside.”

Airflow

Your body also sheds heat when cool air flows over your skin – so on a hot day, you want to wear a fabric that breathes.

Linen also has an advantage here, Jayaraman says. Its fibers are thicker than cotton’s, so linen fabrics tend to have a lower thread count and more openings between fibers. “That means air can more easily pass through,” he said.

But thread counts can vary widely from garment to garment. Shepherd said you should judge the fabric for yourself. “If you can see light through it, then water and air can penetrate through it,” she said.

Linen’s other big advantage is its stiffness. Rigid linen fibers tend to hold their shape better than cotton, causing linen clothing to hang away from your body while cotton clothing tends to cling to your skin. Leaving more space for air to flow between your clothes and your skin cools you down and helps sweat evaporate.

The bottom line

While linen is, scientifically, a cooler fabric than cotton, that’s not the only factor you have to consider when picking out clothes.

For instance, linen’s stiffness – which is so helpful for letting air flow over your skin – might rub some people the wrong way. “Someone might be more comfortable with cotton because it feels nicer. It’s a bit softer,” Shepherd said. “So that comes down to personal preference.”

Linen’s stiffness also makes it prone to wrinkles, requiring more ironing – unless you want to go for a rumpled look. “The wrinkles can make a fashion statement about being a cool guy, pun intended,” Jayaraman said.

“Sometimes the stylish selection goes against comfort. It’s just about what is more important to you,” Yang said. “But I’m a chemical engineer, so unfortunately I know nothing about fashion.” Linen or cotton: Which fabric keeps you cooler in sticky summer heat?
