I think it’s disappointing but not unexpected. Most of the fashion houses that can afford to put on a catwalk show are big businesses whose main goal is to make money, so they are only interested in sustainability if it will sell product. I am aware this is a massive generalisation, and I’m sure lots of brands are moving to make their offering more ethical/sustainable.
There are also plenty of smaller designers who manage to show during fashion weeks who have sustainability embedded at their core, like
Bethany Williams. I think that fashion will have no choice but to evolve in a more ethical and sustainable way. People and the realities of climate change will force businesses to change. Hopefully, sustainability will not be a category anymore; it will just be the structure that underpins creativity.
