Sustainable modest fashion has evolved into a movement that balances spiritual values with ethical responsibility. For Gen Z Muslim women, the priority in 2025 is no longer just finding a dress that covers—it is finding a brand that protects the planet and the workers behind the seams. While industry giants like Modanisa have pioneered accessibility, the modern "connected generation" is shifting toward transparent, slow-fashion labels that prioritize GOTS-certified organic cotton, recycled fibers, and fair-wage production.
