Ethical, responsible, green, fair-trade. You hear these words all the time and maybe don’t think much of them. But with climate change moving at such an alarming speed, maybe it’s time to learn a little about the clothes on your back—and in your online bag.

The clothing industry is the second largest polluter in the world, second only to oil. But with brands like Reformation, Re/Done denim, Everlane and Stella McCartney leading the pack of eco-chic companies bringing you stylish yet ethical clothing, that’s all changing. Even the well-known “fast-fashion” houses like H&M, Zara and Mango have created exclusive collections aimed at being more green and sustainable.

Vintage shopping and utilizing sites like eBay or The Real Real are great ways to help the environment by not adding to fashion’s carbon footprint. Companies like Rent the Runway don’t just make wearing trendy pieces more affordable, but they are “recycling” the same piece of clothing to their customers with each rental.

Between the factories producing the clothing we wear every day to the shocking amount of materials and boxes used to ship that clothing worldwide, it’s no wonder our planet is in trouble. The fashion industry is depleting the Earth’s natural resources one OOTD at a time, but thanks to (fashion) forward-thinking companies and designers, there’s no better time than the present to join the ethical movement.
