Included in the eco collection are a cropped denim jacket, four different jean fits, and a pair of skinny overalls. As for the finer details of Madewell's newfound sustainability methods, it's not taking the easy way out: The brand notes that the products are manufactured using "organically-sourced Italian cotton grown from non-GMO seeds" without using any toxic chemical treatments.
