Looking for another great cause to rally behind? Meet your new excuse to go on a shopping spree -- sustainable clothing. Sustainable clothing has been an up-and-coming trend for years and it's starting to take hold in the fashion industry. The fashion industry is actually one of the worst polluting industries in the world, second only to the oil industry.

The word "sustainable" gets thrown around a lot, but what does it actually mean? Sustainability is basically a fancier word for "eco-friendly." The goal of sustainability is to create an economic system that provides for a good quality of life for people while renewing the environment and its resources. That means that, ideally, instead of using things like natural gas, oil or plastic to create and power stuff, we would use natural, renewable resources like solar power, wind power or plants.

With the Trump administration's apparent disregard for environmental preservation, it's more important than ever to support sustainability efforts. Of course, there are many small things you can do to live a greener lifestyle. But have you ever considered making your wardrobe more sustainable? Sustainable fashion focuses on creating classic designs that will last you for years as opposed to the more unethical "fast fashion" trends that create waste and harsh working conditions. The main goals of sustainable fashion are to use organic materials, minimize waste and maintain Fair Trade standards.

Now, I know what you're thinking -- there's no way I'm going to wear plant clothes! Hemp is only for hippies! But these brands are as stylish and classic as they are eco-friendly and practical. So buy some cute clothes, stand up for a cause you believe in and save the planet!
