IN HOUSE launches a suiting collection featuring Spiber’s Brewed Protein™ fiber
Spiber is pleased to announce that New York-based made-to-order fashion brand IN HOUSE has released a new suiting collection featuring Brewed Protein™ fiber.
IN HOUSE, known for its dedication to innovative and sustainable design, has become the first U.S.-born brand to adopt Brewed Protein™ fiber. This collaboration marks an important milestone in Spiber’s efforts to expand its materials into the U.S. fashion market.
Launched in September 2025, the collection consists of six tailored pieces—the Zip-Up Blazer, Button-Up Blazer, Work Skirt, Work Pant, Skirt Pant and Double Skirt—with only the black color versions crafted from a wool blend fabric that incorporates Brewed Protein™ fiber.
Each item is available through a made-to-order system and is currently sold exclusively within the United States.
