Introduction

Glenn Martens is stepping down as creative director of Diesel after six years to devote his full attention to Maison Margiela. His final runway show in Milan next week will serve as his last presentation for the Italian denim house.

What Happened

Martens, a Belgian-born designer who studied at the Royal Academy of Fine Arts in Antwerp, previously led Y/Project from 2013 to 2024, building it into a cult experimental streetwear label. He was appointed Diesel's creative director in October 2020, tasked with reigniting a brand that had faded from the cultural conversation. Over six years, he redefined Diesel’s aesthetic through distressed denim, exaggerated silhouettes, fringe details, and provocative show concepts—including a Fall 2023 presentation featuring Durex condom boxes and a moaning soundtrack. The revamp attracted high-profile fans such as Rihanna, Beyoncé, and Julia Fox.

Why This Matters

Martens simultaneously served as head of Maison Margiela since 2025, following John Galliano’s departure. Both brands are owned by OTB, and his dual role meant Diesel often took a backseat to Margiela’s priorities. With his departure, the brand must now chart a new creative direction while preserving the cultural momentum he built. The fashion world will watch closely how Diesel appoints a successor and whether it can sustain the relevance Martens forged.

Conclusion

While his legacy at the brand is firmly established, the coming months will reveal how Diesel navigates the transition and whether it can maintain the cultural relevance he cultivated. Meanwhile, all eyes remain on Margiela, where Martens will now concentrate his creative energy.
