Upcycling Vintage Materials: The brand's signature method is sourcing and repurposing high-quality antique and vintage lace, silk shawls, veils, curtains, and bedspreads found in markets, antique stores, auctions, and estate sales across Europe (primarily France and the UK).

Natural Fibers: They exclusively use natural fibers like cotton and silk, avoiding synthetic materials (nylon, polyester) which produce micro-plastics and have a high carbon footprint during manufacturing. New silk used for linings is OEKO-TEX® certified.

Low Carbon Footprint: By reusing existing materials, they significantly reduce the carbon footprint and water consumption associated with creating new fabrics.

Ethical Local Production: All gowns are ethically handcrafted in their Sydney, Australia, atelier (studio). The company ensures fair working conditions and avoids sweatshops.

Made-to-Order & Made-to-Measure: Dresses are generally made-to-order or in small batches to minimize excess stock and fabric waste. International customers can utilize a complimentary virtual consultation service.

Artisanal Craftsmanship: Each gown is handmade from start to finish by a single seamstress, sometimes incorporating work on century-old sewing machines, providing a unique and personal touch.

Zero-Waste Goal: The brand strives for zero waste in its production. Large lace scraps are reused in patchwork designs (such as the "Edwardian" dress), while smaller scraps are composted.

Customization and Collaboration: Lost in Paris offers a collaborative design approach, allowing brides to customize designs or incorporate their own family heirloom materials into their dress.
