Cecilie Bahnsen confirmed that its factories in Copenhagen are B-Corp certified and pay living wages. Reformation reported that its denim collection was manufactured in a factory in Los Angeles that holds Fair Labor Association (FLA) certification. All three brands published full material sourcing details on their websites, including fiber origins and production locations.

Consumer Availability and Price Comparisons

The Prada Re-Nylon 2025 collection is priced at $650–$2,400, which is higher than average for recycled nylon products. For comparison, the sustainable brand Outerknown offers a recycled nylon jacket for $420. The Cecilie Bahnsen Zero Waste collection ranges from $320–$1,200, with a $320 midi dress being 20% more expensive than a similar organic cotton dress from Everlane. Reformation’s recycled denim line starts at $145, which is comparable to Eileen Fisher’s recycled cotton denim at $150.

What’s Next for Sustainable Fashion

These collections are part of a broader trend in luxury and contemporary fashion. In December 2025, 12% of major fashion brands announced new eco-materials initiatives, up from 8% in November. The shift toward recycled textiles is growing, with brands like Stella McCartney and Patagonia already using similar materials. The fashion industry has not yet adopted a universal standard for recycled content reporting, but organizations like the Textile Exchange are pushing for greater transparency. In 2026, the European Union is expected to introduce mandatory sustainability labels for all clothing sold within its borders.
