What is Kings of Indigo?

Kings of Indigo, often abbreviated KOI, is a denim brand from Amsterdam. Its website describes it as an Amsterdam sustainable fashion brand since 2012, aiming to make the highest quality denim with the lowest impact.

Products and positioning

The core product is the five-pocket jean, offered in women's and men's cuts including skinny, straight, tapered, loose and flared. The range also covers denim jackets, corduroy pieces, tops, bottoms, outerwear and accessories. The brand sits in the premium segment, where price is justified by durability and responsible production.

  • Five-pocket jeans in a range of cuts
  • Denim jackets and corduroy pieces
  • Tops, bottoms, outerwear and accessories

Sustainability and traceability

Sustainability is the brand's central claim. According to its website:

  • Customers receive free repairs under a three year warranty.
  • QR codes on labels let customers trace a garment from fibre to finished piece.
  • The brand works with responsible production partners.
  • It measures its impact by how long a garment stays in use.

Kings of Indigo and technology

The QR code labels are a documented example of digital product information in apparel. They connect each physical garment to supply chain data, which anticipates the digital product passport requirements being introduced in the European Union, though the brand's own pages do not describe any such regulatory plan.

Business model and distribution

The brand has a physical store in Amsterdam and an online shop. Wholesale partners, store counts and revenue are not given in the source consulted. No owner or founder is named on the page, so none is stated here.

Why it matters

Kings of Indigo is a clear case of a denim brand making repair, longevity and traceability part of its business model rather than a marketing add-on.
