Is the prevailing fast fashion model sustainable? What alternatives are there? Fairtrade? Democratic workplaces? Do you know of any businesses or networks that are modelling something different? How can you support them?

Fast fashion and sustainability are an oxymoron. The whole idea behind fast fashion is to churn out cheap new collections and stimulate consumption, and there's nothing sustainable about that. It's impossible to produce ethical, eco-friendly clothing at the quantity and rate that fast fashion demands while maintaining genuinely high and environmentally sustainable standards. Fairtrade is good alternative, a buisness that does this is "Faʻamolemole", you can support them by not supporting fast fashion.

Fast fashion companies' codes of conduct are not sufficient and do not improve the working conditions in garment factories ... Domestic and international law can be changed to improve this by setting global working conditions and wage standards.

Explanation:

Many clothing companies are choosing to manufacture overseas due to much lower production costs. Many lesser developed countries do not have strict labor laws like the United States, and have very low minimum wages, if there is one at all.
