Sustainable fashion originated at the fringes, pioneered by a handful of designers advocating for ethical production and environmental conservation. Initially, mainstream brands paid little attention, viewing sustainability as costly or antithetical to traditional practices. However, mounting ecological crises, exposés on labor conditions, and influential social movements gradually shifted public opinion. As a result, sustainability became an expectation rather than an exception, prompting even the largest players to adapt their business models and embrace eco-friendly initiatives. Today, the majority of major retailers incorporate some form of sustainable practice, reflecting the movement’s widespread impact.
