I think fast fashion is one of the things that seems like a need because everyone wants to keep up with trends, but it's actually a big want that causes a lot of problems. It's tempting because you can get a whole outfit for like $20, but the quality is usually so bad that it ends up in the trash after a month. In my opinion, it's much better to save up for at least a quality piece of clothing that you like instead of buying five cheap things just because they're on sale. Plus, the environmental impact is huge, fast fashion creates so much waste. If more people just shopped at thrift stores or wore their clothes longer, it would save money and the planet.
