When you pull on a Citizen Wolf T-shirt, odds are it will be the most comfortable, best-fitting piece of casual fashion you'll ever own. Oh, it's also helping to save the world.

Shamefully, fashion is the second most polluting industry on the planet - and most of us are guilty of feeding the beast. But Citizen Wolf is looking to change that. In this episode of Telltale we speak with the co-founder of sustainable fashion brand Citizen Wolf, Eric Phu. The casual clothing brand makes custom, tailored, handmade outfits for its customers but also focuses on creating a sustainable business with a low environmental impact.

But it didn't start that way.

Eric explains that the problem Citizen Wolf aimed to solve was customising and tailoring clothing to ensure a proper fit and a long-lasting, high-quality garment. It just happened to be a byproduct, he says, that the brand's process focused on doing so sustainably. But it's an important point of difference.
