‘It gives Shein’: how did polyester become the world’s most-hated material?
Gen Z is increasingly using "polyester" as an insult, reflecting a widespread backlash against the synthetic material due to its ubiquity in fast fashion, environmental impact, and perceived cheapness.

The article explores how polyester, once a popular fabric, has become a symbol of cheapness and poor quality, particularly among Gen Z. This generation is actively pushing back against the material, linking it to fast fashion brands like Shein, expressing concerns about its feel, health implications, and environmental damage, while also influencing broader consumer trends towards natu…
Imagine a cheap plastic toy that breaks easily and feels yucky. That's kind of how many young people now see polyester, a fabric used in lots of clothes, especially super cheap ones from stores like Shein. They don't like how it feels, how it looks, or that it's made from oil and sheds tiny plastic bits. So now, calling something "polyester" is like saying it's cheap and uncool.

Shein's Shifting Fortunes
The Chinese ultra-fast fashion giant Shein has become synonymous with cheap, polyester-heavy clothing, influencing consumer perception of the material. Its business model, characterized by extremely low prices and rapid production, has made polyester ubiquitous in the fast fashion sector. However, Shein's market standing is undergoing a significant re-evaluation, with its valuation plummeting from $100 billion in 2022 to an anticipated $27 billion for its upcoming Hong Kong stock exchange listing.
This decline is attributed not only to the rise of similar "polyester" (in the Gen Z pejorative sense) offerings from competitors like Temu and Amazon but also to external economic pressures. Donald Trump's trade policies have reportedly made it challenging for Shein to maintain its aggressively low pricing strategy, impacting its competitive edge. The company's ubiquity has also inadvertently elevated other fast fashion brands, making them appear "mid-market" to young consumers who now expect higher quality for higher prices.
Gen Z's Polyester Pushback
Generation Z, defined as those born between 1997 and 2012, is at the forefront of a cultural and economic backlash against polyester. This demographic uses "polyester" as a pejorative term for anything perceived as cheap, inauthentic, or uncool, reflecting a broader dissatisfaction with available fashion choices. Their concerns extend beyond aesthetics to include the material's environmental footprint and potential health implications.
Young consumers are increasingly vocal about polyester's derivation from fossil fuels, its non-biodegradable nature, and its propensity to shed microplastics during washing. Health worries also play a role, with studies suggesting that dyes, flame retardants, and sweat-wicking chemicals in synthetic fabrics can leach into the skin, particularly from activewear. This has fueled a trend towards natural fibers like cotton and linen, with influencers promoting "nontoxic clothing" and "naturalfibers" hashtags, even if their shopping habits sometimes still involve fast fashion retailers.
USDA's Cotton Initiative
Amidst the growing consumer aversion to synthetic materials, the United States Department of Agriculture (USDA) has launched its "Plant Not Plastic" initiative. This program aims to revitalize the American cotton industry, which has faced significant challenges from rising costs, foreign competition, and the influx of inexpensive synthetic products. The initiative underscores a broader economic and political push to support domestic agricultural sectors.
The sentiment for natural fibers has also found a voice in political campaigns, with figures like RFK Jr. using imagery of "Real Americans wear cotton" to resonate with a demographic valuing authenticity and domestic production. This convergence of environmental concerns, consumer preferences, and national economic policy highlights a potential shift in material sourcing and manufacturing. The USDA's efforts represent an attempt to rebalance the market away from fossil-fuel-derived synthetics towards more sustainable, domestically produced natural alternatives, potentially reshaping supply chains and agricultural practices.
Key points
- Gen Z is increasingly using "polyester" as a pejorative term for cheap or uncool items, reflecting a broader dissatisfaction with the material.
- The backlash against polyester stems from concerns about its cheap feel, potential health impacts from chemicals, and its environmental footprint as a fossil fuel-derived, non-biodegradable material that sheds microplastics.
- Shein's valuation has dropped significantly from $100bn to $27bn, partly due to competition from similar brands and the impact of trade policies.
- The USDA has launched a "Plant Not Plastic" initiative to revitalize American cotton, aiming to counter the dominance of cheap synthetic products.
- Consumer preference is shifting towards natural fibers like cotton and linen, influencing purchasing decisions and fashion trends.
The growing consumer demand for natural fibers could drive innovation in sustainable textile production and revitalize traditional agricultural sectors like cotton farming. This shift might lead to higher quality, more durable clothing options and reduce the environmental impact of the fashion industry.
Despite the backlash, the allure of extremely cheap clothing may continue to drive demand for synthetic materials, perpetuating environmental concerns and health debates. Fast fashion brands might adapt by greenwashing or finding new ways to produce low-cost synthetics, hindering a genuine shift towards sustainability.
