I just took the @thredUP fashion footprint quiz to see how dirty my closet is. Spoiler alert: Shopping secondhand is the BEST way to clean it up. Take the quiz to find out your carbon impact and what you can do about it. Plus, get some really awesome sustainable tips and exclusive offers! For every public share with #FashionFootprint and @thredUP, they’ll donate $1 to the thredUP Circular Fashion Fund, dedicated to supporting sustainable fashion efforts worldwide.
