Fashion and 'sustainability' don't actually go together. A garment is usually made in such a way that it quickly goes out of fashion, FashionUnited reported.
In the fashion industry there is not only stylistic obsolescence, but also technical obsolescence. Some clothing is of such low quality that it tears, pills or loses its colour after a few wears and washes. Ideal for fashion companies that rely on the sale of new garments, but not on sustainability.
Therefore, the answer to the question of how sustainable the fashion industry is is: not much/not yet.
In the clothing industry, profit usually comes before people and planet, or people and the environment.
The Belgian journalist Sarah Vandoorne, who specialises in sustainable fashion, said in the introduction to her recently published book 'Kleerkastvasten' (which translates into ‘Wardrobe Fasting' in English) : “Day in and day out, we put on clothes. They are part of our identity, they make us feel good about ourselves. At the same time, millions of people are working their butts off for a pittance to dress us, and the fashion industry is, in the process, also helping to kill our planet.” /BGNES
