Greta Thunberg has graced the front cover of Vogue and urged the industry to move away from fast fashion.
Loads of retailers rely on cheap labour to mass produce their clothing that doesn't last very long, leading to consumers throwing it out and buying it new again.
The Swedish climate activist has used her platform on arguably fashion's biggest trade name to steer customers away from this trend and buy things that made from better quality materials.
"If you are buying fast fashion then you are contributing to that industry and encouraging them to expand and encouraging them to continue their harmful process," she told Vogue.
"Of course I understand that for some people fashion is a big part of how they want to express themselves and their identity."
The amount of textile waste being generated has been increasing year on year.
Sustain Your Style claims the average family in the Western world will get rid of a whopping 30kgs of clothing each year.
Their data indicates that only 15 per cent of that clothing goes to being recycled or donated.
Greta wants fashion labels to think more about sustainability and not commit to pointless campaigns that only scratch the surface of the issue.
She told her followers on Twitter: "The fashion industry is a huge contributor to the climate-and ecological emergency, not to mention its impact on the countless workers and communities who are being exploited around the world in order for some to enjoy fast fashion that many treat as disposables.
"Many make it look as if the fashion industry is starting to take responsibility, spending fantasy amounts on campaigns portraying themselves as 'sustainable', 'ethical', 'green', 'climate neutral' or 'fair'.
"But let's be clear: This is almost never anything but pure greenwash.
"You cannot mass produce fashion or consume 'sustainably' as the world is shaped today. That is one of the many reasons why we will need a system change."
Some people on social media have praised the teenager's message and called her Vogue photoshoot the best cover in history.
However, others have pointed out that fast fashion is sometimes the only option for poorer individuals who can't fork out $50 for a t-shirt.
For these people, they have to rely on cheaper clothing brands to ensure they have something to wear each day.
The wider issue is raising people out of poverty.
