This dress was unveiled in the brand’s new collection, presented at Paris Haute Couture Fashion Week Fall/Winter 2025, as one of two bridal looks that attract attention in each collection. The intersection of learning from nature and creativity Spiber and Iris van Herpen were both founded in 2007 and have been innovating in their respective fields. Spiber has been developing its own protein material through biotechnology, inspired by natural structures such as spider silk, cocoons, and cashmere fibers, while Iris van Herpen continues to present avant-garde couture inspired by the natural world. The two share a deep connection, such as respecting the mechanisms of nature while facing its essence from a new perspective, which led to this collaboration. Iris van Herpen Designer | Comment from Iris van Herpen “Spiber’s approach is always alive with the spirit of biomimeticism, which is deeply connected to our methodology. I was very impressed with their fusion of organic ideas and advanced technology, and their new approach to the question of “what is a material?” The Brewed Protein(TM) fiber I used this time has the lightness and softness I want, and a unique feeling that seems to float around the skin. The natural, organic presence spread naturally throughout the work. The Spiber team and I feel a common aesthetic sense in terms of the texture of the material and attention to detail.” About the composition of the work In this work, Brewed Protein(TM) fiber plays an important role as a structural material. A sheer organza with a gradient cut to resemble the shape of the moon is heat-bonded to a laser-cut framework of the same material, and hundreds of white petal-like parts are sewn onto nude-colored tulle. They flow in a swirling pattern, forming a translucent train. Image

Materials have the potential to tell stories, evoke emotions, and redefine our relationship with nature. It was a very special experience to encounter Iris van Herpen’s design, which gives form to the essential beauty of the complexity of life, and to find that our philosophy resonated deeply with her. Brewed Protein(TM) fiber was born from Iris’s creative fountainhead, asking questions of nature and continuing to pursue its possibilities, rather than merely answering them. This collaboration is not just about creating a material to wear, but also about presenting a way of experiencing the material, and we see it as a step toward the future of fashion in terms of both sensibility and structure. We are truly proud of this encounter, and hope that this initiative will be an opportunity to build a new relationship with creativity, sensibility, and nature. ” Future Outlook This bridal look is not just a fashion show moment, but was born from the shared belief of both parties that collaboration across disciplines is the key to addressing the complex challenges facing fashion and the global environment. Both the Spiber and Iris van Herpen teams will take this initiative as a new starting point and continue to explore the possibilities of materials. Iris van Herpen Since its founding in 2007, Iris van Herpen officially joined the Federation de la Haute Couture in 2010. By combining traditional couture techniques with innovative technology and materials, she has created sensory-inducing pieces that poetically reflect the intricacy and diversity of the natural world. Their designs are a quest for beauty that transcends boundaries, involving not only the visual sense but also the sense of touch and atmosphere, opening up new horizons in contemporary couture. Brewed Protein(TM) Fiber A high-quality fiber material made using Spiber’s unique fermentation (brewing) technology based on
plant-derived raw materials. It enables circular manufacturing and pioneers a new material category, “protein” fiber. Brewed Protein(TM) fiber is engineered to have the luster and fineness of silk, the fine smoothness of cashmere, and the bulkiness of wool. In addition, thanks to its plant-based ingredients and precise fermentation process, Brewed Protein(TM) fiber is expected to have significantly reduced impacts on the environment and animal welfare compared to conventional materials. Spiber Inc. A bio venture company founded in 2007 and headquartered in Tsuruoka City, Yamagata Prefecture. The company is committed to creating innovative solutions to contribute to
sustainable well-being and solving environmental issues. The Brewed Protein(TM) material platform developed by the company utilizes precision fermentation technology, allowing the properties of the material to be designed at the molecular level to suit the
application, and is expected to realize sustainable and
high-performance material solutions in various fields such as apparel, food, and automotive industries. To pave the way for a promising future, Spiber is constantly exploring the possibilities of various applications of Brewed Protein(TM) materials, minimizing the impact on the environment while contributing to a circular society, and continuing to work tirelessly to build an inclusive, fair, and regenerative world.
