When it comes to sustainability and ethics, the
sustainable fashion
movement has a lot to be proud of. However, how accessible it is may be a different story. One of the most notable flaws in slow fashion is its lack of plus-size sustainable clothing options.
Inclusivity is crucial in getting more people on board with eco-friendly fashion. Unfortunately, many of the most popular sustainable brands carry a very limited selection of sizes. A 2016 survey published in the
International Journal of Fashion Design, Technology, and Education
found the average size of an American woman is between 16 and 18, yet most clothing lines still only carry up to a size 12.
Accessibility is one of the most important aspects of slow fashion that needs to be looked at, and it's necessary that everyone feel included in a movement that's supposed to be advocating for a better world. We've compiled a list of plus-size sustainable clothing brands that are putting in the work to make ethical clothing available to all.
