A look back at our Dutch Sustainable Fashion Week pop-up in Amsterdam

There’s something about seeing independent fashion in person that changes the way you experience it.

Online, you might notice the silhouette of a jacket or the shape of a bag. In person, you feel the fabric, try something on, notice the small details in the construction and, often, get to hear directly from the person who made it.

That was exactly what we wanted to create with our latest Closet.eco pop-up during Dutch Sustainable Fashion Week: a space where people could slow down, discover independent designers and experience a different side of sustainable fashion in Amsterdam.

For one day, we brought together four very different brands — KONINA, Nounou, COSLI and tote — each with its own approach to materials, production and design. From made-to-order silver jewellery and natural-fibre workwear to recycled crochet bags, the event was a good reminder that sustainable fashion doesn’t have one particular look.

four brands, four very different approaches to fashion

One of the things we enjoy most about bringing brands together physically is seeing just how broad the idea of responsible fashion can be.

There is sometimes still an assumption that sustainable fashion has to follow a particular aesthetic: neutral colours, simple basics, perhaps a lot of linen. But the brands participating in our Dutch Sustainable Fashion Week pop-up showed something very different.

Each approached sustainability from a different angle, whether through materials, made-to-order production, craftsmanship or the reuse of existing resources.

Nounou: jewellery made only when someone wants it

Nounou takes a slower approach to jewellery, creating made-to-order pieces in silver and natural stones.

Made-to-order production is a relatively simple idea, but it changes the logic behind how products are created. Instead of producing large quantities and hoping everything eventually sells, pieces are made in response to actual demand.

For an independent jewellery brand, that can mean less unnecessary stock while allowing more attention to go into each individual piece.

The use of natural stones also means subtle differences become part of the design. Rather than expecting every item to look completely identical, the variation in the material makes each piece feel slightly more personal.

COSLI: rethinking what office clothing can be

Workwear is an interesting part of the sustainable fashion conversation because these are often some of the hardest-working clothes in our wardrobes.

COSLI focuses on office clothing made exclusively from natural fibres, offering an alternative to the polyester-heavy fabrics that dominate much of conventional workwear.

Natural fibres can offer very different qualities when worn throughout the day, particularly in terms of breathability and feel. But what we particularly like about COSLI’s approach is that sustainability is built into a category people genuinely need and wear repeatedly.

Responsible fashion becomes much more useful when it isn’t treated as something reserved for special occasions. A well-made shirt, trouser or office staple can become one of the most frequently worn pieces in someone’s wardrobe.

tote: turning recycled T-shirt yarn into everyday bags

Tote has become a familiar name within the Closet.eco community, and its colourful crochet bags brought a playful element to the pop-up.

The bags are handmade using recycled T-shirt yarn, turning existing textile material into lightweight accessories designed for everyday use.

It is a straightforward example of circular design: taking a material that already exists and finding another purpose for it instead of automatically starting with virgin resources.

And perhaps more importantly, the sustainability story doesn’t overshadow the product itself. The bags are practical, easy to wear and distinctive first; the recycled material is part of how they are made, rather than the only reason to want one.

why physical events still matter for independent brands

For emerging designers, getting people to discover the brand in the first place is often one of the biggest challenges.

Most don't have stores. Many produce very small quantities, and some exist almost entirely online. Competing for attention with fashion companies that have enormous advertising budgets is difficult, even when the product itself is exceptional.

Pop-ups create a different environment.

Someone might arrive interested in one brand and leave having discovered three others. They might try on something they would never have clicked online, speak to the people behind the collection, or finally understand why a particular material or production method costs more.

That kind of discovery is difficult to reproduce digitally.

It’s also why events like Dutch Sustainable Fashion Week matter. They bring the conversation around sustainable fashion out of reports, regulations and marketing claims and place the actual clothes — and the people making them — at the centre.

sustainable fashion is better when it feels normal

For us, the goal of events like this isn’t to convince people to build a perfectly sustainable wardrobe overnight.

It’s simply to make independent, more responsibly produced fashion easier to discover.

Sometimes that means learning about made-to-order jewellery. Sometimes it means finding an office piece made without synthetic fibres. Sometimes it’s discovering that the crochet bag you love happens to have been made from recycled T-shirt yarn.

Those individual decisions may look small, but collectively they support a fashion system built around more thoughtful production, better materials and independent creativity.

Thank you to KONINA, Nounou, COSLI and Tote, and to everyone who came by, tried things on, asked questions, joined the workshops and spent part of Dutch Sustainable Fashion Week with us in Amsterdam.

Until the next one.
