You're surely familiar with Stella McCartney's luxurious handbags, cool sneakers, and minimal-chic clothing. But did you know her brand's ethos is rooted in ethical practices and sustainability? As for her jeans, they're made from organic cotton (and have been 2008!) which uses up to 70% less water than conventional cotton and are void of toxic chemicals. For Fall 2020, the brand, in partnership with Italian manufacturer Candiani, is launching the world's first biodegradable stretch denim made from plant-based yards.
