Y/Project, Constraints, and Resetting Diesel

Belgian designer Glenn Martens grew up in Bruges, studied in Antwerp and cut his teeth in Paris, where lean years taught him every role from pattern cutting to PR. At Y/Project, he turned constraints into modular, shape-shifting design. At Diesel, he reset the brand around its founding spirit of joy, cheekiness and denim, replacing muddled codes with a clear manifesto and democratic shows that speak to a global community. Now balancing Diesel with Maison Margiela, Martens argues that fashion should make people happy while resisting the dopamine churn of instant judgement.

“We are just consuming visuals and we don't really have the time to go deep into the clothes, the storytelling, the construction, where it comes from. It just needs to be like a hit. It gets a bit more superficial,” he shares with Imran Amed, BoF founder and CEO. “In 2025, a creative director has to be a socialite, has to be the king of social media and  there's so many more things that all my colleagues and I have to do outside of that runway. The beauty of fashion is it's a process and it's a build-up and it’s not happening in one show – this is happening in three, four, five shows. So we need to respect that and celebrate that.”

This week on The BoF Podcast, Amed sits down with Martens to talk about learning every job in the studio, rebuilding Diesel around its founding values, as well as the pressure and possibility of this high-stakes season.

Key Insights: 

• Martens argues that the industry’s chase for quick hits has flattened nuance, yet he is determined to hold the line on depth and craft. “There is definitely a big part of me that loves to deep-dive into storytelling and construction, that likes to challenge construction and try to find new ways to create beauty and new ways to create clothes. I am very easily bored; I need to challenge myself. I love experimentation and that makes me happy.”

• At Diesel, Martens began by reconnecting the house to its core DNA. “My biggest thing I did was resetting the whole thing and reminding everybody why Diesel was big in the first place. And I think that is something that is really important to never forget, that the success of a brand is the core reason why the brand is there and we should always connect to that and stay close to that.” He underscores the scale and breadth of the audience while keeping a unified voice. “We are so diverse in our markets, so we are basically talking to everybody. Every single person in the world could, in theory, be a Diesel person, but we do that with one message and with one collection.”

• Martens is now continuing to turn the runway into a democratic platform that includes the wider community, not just the front row. “I think a fashion show for us is very important because it accelerates the awareness of the brand and the direction you want to go. [Diesel] is talking about democracy. It is at heart a lifestyle brand.” For Diesel’s Spring/Summer 2026 show next week, Martens is pushing shows into public space to meet people where they are. “The launch of that collection will be in the streets of Milan. It is going to be a three-and-a-half-hour egg hunt, showing the whole diversity of the town, and everybody can participate.”
