A smart tweed suit is shorthand for Chanel. For its Cruise 2021/22 collection, the storied French fashion house gave the fashionable classic a sustainable makeover, introducing what it refers to as “eco-responsible fabrics.” Twenty-eight of the 78 looks in the collection were made using more than 70 percent of these new textiles, which are GOTS- and GRS-certified. And that includes the iconic tweed suit. For a luxury brand that has been using the finest materials for decades, incorporating recycled fabrics is a big deal, and especially symbolic when you consider that it’s being used for its legendary tweed. But at a time when greenwashing is rampant, we wanted to know what it really means when a global leader like Chanel makes sustainability claims about its materials.
