One of the ways we can confront the climate crisis in a realistic way, is to avoid buying fast fashion. The manufacturing from fast fashion results in a large use of fossil fuels as many popular companies require shipping overseas. 
Roughly ten percent of annual global emissions are from fast fashion and it takes second in being the largest consumer of worlds water supply. Majority of the clothes are discarded annually, ending up in landfills or being burned. The environmental impacts can be avoided if consumers choose to avoid investing in such companies and resort to more sustainable options, such as shopping for vintage and recycled fashion items. We can also choose to wear clothing that has good, long-lasting materials that release less carbon emissions. We can learn to mend and repair, and use ways to make clothes last longer. Supporting sustainable fashion companies and donating are additional ways we can play a role in reducing our carbon footprint.

This is a great point. There are so many great alternatives to fast fashion there aren't necessarily more expensive. Thrifting, buying from small businesses, and making your own clothes are all great options which are not only better for the environment, but can also have benefits like finding original and unique pieces.
