Our Story.
From love to responsible fashion — two people from Lyon, one shared conviction.
Garçon Fidèle was born from a simple question: why is it so difficult to dress well without harming the planet?
"We met in October 2023, in Lyon. Since that day, a love continues to grow, based on unity, ambition, travel, and the desire to build something that reflects us. Thus, in 2025, the idea of creating a textile brand based on strong ecological values and social ties was born. After several months of reflection, we found our motto: responsible and local fashion that carries a clear message. We are committed to supporting local actors and making a positive impact on the world around us."
