There are a number of solutions to make fashion "greener", some of which will be on display at London Fashion Week, reports AFP.
Designer Ray Chu has created a vegan leather made using recycled tea leaves while Romanian designer ̦Ancuta Sarca uses recycled materials in her footwear collections.
But such innovations could struggle to keep up with the scale of emissions and textile waste.
Some 300 tonnes of clothes are binned every year in the UK, according to a 2020 British parliament report.
Since then, the popularity of fast fashion brands like H&M and Zara, and ultra-fast fashion brands like Shein and Temu, has only grown.
Such brands sell cheaply made, mass-manufactured clothes at breakneck speeds, only for them to fall apart or be discarded after being worn a few times.
While many brands are turning to recycled materials, or offering clothing repair or rental services, the long-term solution seems to be to "slow down our habits of consumption in general", said Hakansson.
To help with this, people could work towards "cultivating a sense of personal style", she suggested.
"If you don't know what you as an individual like, then you're much more likely to follow these micro trends that are being really pushed on us very hard," Hakansson added.
With greater awareness of the challenges posed by climate change, shopping second-hand has become more popularity, noted Garnett.
"The kids have basically got the idea that... second hand -- it's a cool way to shop. By finding your own style, a one-off piece, it (becomes) like a style choice."
