The forward-thinking designers you must know about in 2025

Curious which designers will transform the fashion world in 2025? As the CEO of COSH!, it is both my passion and responsibility to spot forward-thinking designers who create collections that seamlessly integrate technology and sustainability.

For 2025, I am excited to highlight some truly inspiring names. These designers go back to the essence of fashion: whether it is through clean cuts and precise patterns, lovingly crafting with natural materials like grandma used to, or creatively upcycling. Their drive to design as sustainably as possible — using natural fibres and yarns such as linen, organic cotton, or repurposed fabrics—makes them stand out in circularity and zero-waste solutions. These are the designers you simply need to know about!

Pioneering fashion with authenticity

Hul le Kes is undoubtedly one of my absolute favourites. Their collections shine with a unique combination of authenticity, craftsmanship, and sustainability. They challenge traditional norms by introducing sizing from 0 – 5, based on how you want your garment to fit, and designing gender-fluid fashion.

Imperfection is elevated to an art form, celebrated as powerful symbols of authenticity. Using antique linen, vintage fabrics, and leftover materials — 95% of which, they claim, comes from post-consumer or production waste — they prove that fashion can be both meaningful and responsible.

Their latest collection (SS25) launches in February 2025, and I have already had a sneak peek. One tip: it is going to be stunning!

Free Prisoner

Finding beauty in impermanence with Rust

When I received an email from Amber about Free Prisoner​’s latest collection, Rust, I was immediately captivated. Inspired by the search for beauty, impermanence, and inner peace, the collection reflects life’s natural transitions, much like the process of rust forming.

Using rust as an artistic tool, Amber creates unique patterns that celebrate imperfection and decay. Her commitment to zero-waste design and slow fashion highlights how innovation and sustainability go hand in hand. This collection invites you to reflect on the beauty of change and embrace a more conscious, sustainable lifestyle.

Natascha von Hirschhausen​’s collections are the epitome of zero-waste fashion. Every piece is produced locally in Germany with a process that reduces fabric waste to an absolute minimum — less than 1% according to Natascha, compared to the significant material loss during the typical cutting process in fashion.

Her approach goes beyond efficiency; it is a conscious choice that prioritises transparency, fairness, and sustainability. With this philosophy, Natascha inspires systemic change, placing environmental and social values above profit.

tiSHōō

Seasonal chapters: the power of materials

tiSHōō is breaking fashion conventions with their chapter-based collections. Each chapter tells the story of a specific fabric, with new pieces gradually added to the existing chapters.

What I admire most about Sabine’s work is the exclusivity, not just in small batches and limited editions, but also through her conscious use of deadstock materials from overproduction.

An interesting detail: on the website and via hangtags, you can see exactly which edition your item belongs to and how many were made. Every garment carries not just a story, but a unique identity.

Good Time Charlie

Warm, wearable art

Good Time Charlie has redefined luxury with coats that radiate class, craftsmanship, and a more sustainable lifestyle. Each piece is lovingly crafted from carefully selected vintage blankets, each with its own story and rich history. This makes every design not only unique but also a true work of art.

With an unparalleled attention to detail, Good Time Charlie takes upcycled fashion to the next level. These coats are more than just functional—they are soft, cosy, and feel like a warm, loving embrace, combining style and comfort effortlessly.

Souâd Feriani

Slow fashion elegance by women, for women

Souâd Feriani celebrates feminine beauty in such a remarkable way that it always resonates with me. Her collections embrace the diversity of body shapes, reflected in her designs that range from size XXS to XXL. That her clothing is made by women for women only adds to the power of her work.

Each piece is produced in small batches and carefully fitted on women of various sizes before the gradation is finalised in the factory. This process underscores her commitment to slow fashion — collections that are not rushed, but grow and evolve organically.
