The True Cost of Sustainable Ethical Fashion

We believe you deserve to understand what you're paying for.

Every ADKN garment is priced to reflect the real costs behind creating truly ethical, sustainable fashion, without shortcuts or compromises.

From initial design to marketing, production, and aftercare, everything is handled in-house by our dedicated team in London, all paid fairly for their craft and expertise. Our materials are bespoke-developed for ADKN, always vegan, recycled or organic, ethically sourced, made to last and never mass-produced.

Each piece is produced in-house in small, zero-waste batches, using green and responsible practices and thoughtful design to reduce excess.

We also work differently to reduce waste from the inside out. A part of our collection is made by salvaging leftover materials and past designs or samples, carefully reworking, refining and restoring them into unique, revived pieces. This second-life approach allows us to honour resources already in circulation, extend their lifecycle, and create something new without creating unnecessary waste.

Our commitment extends beyond the garment: we use recycled and recyclable packaging and carbon-conscious logistics to reduce our environmental footprint from studio to doorstep,
because sustainability doesn’t stop at the product; it runs through every part of our process.

This isn’t just a price tag. It’s a reflection of the time, care, and integrity that go into making true ethical slow fashion.

By choosing ADKN, you're investing in a system that values people, animals, and the planet, not margins or trends. This is fashion that respects every thread of its journey.

A silhouette-hugging long dress with new take on a sweetheart neckline and a high slit perfect for a special occasion. Extremely soft and light, this dress is made from 100% Recycled Crepe for none of the nasties but all of the glam! Closes with a concealed zip on the back.
The ADKN Repair Promise

Because what’s made to last, deserves to be looked after

At ADKN, we believe that quality is a responsibility, not just a feature. Every garment we create is made with craftsmanship, care, and longevity in mind. And to honour that, we offer complimentary repairs for up to one year from the date of purchase, because we believe in standing by the quality of what we make, and extending the life of what you love.

After one year, we're still here for you. Repairs beyond the first year are available for a small fee, based on the service required. It’s our way of supporting thoughtful ownership, not disposability. This is our way of standing by what we make, and helping reduce the waste that fast fashion leaves behind.

Every ADKN piece is ethically made in our London studio, within a trusted supply chain. Fair wages. Responsible processes throughout.

Sustainability Without Compromise

Every piece is thoughtfully crafted in small batches or on demand in our zero-waste London studio, using certified sustainable, vegan and responsibly-sourced materials. No cruelty, no compromise. Made to be worn, loved, and re-loved.

Timeless Designs That Last - Guaranteed

Rooted in slow fashion principles, our collections are intentionally designed to transcend trends, so you can wear what you love, season after season, over and over again. All our products are designed for longevity, backed by our free repair promise. If your garment ever needs mending, we're here to make it right - for you and the planet with The ADKN Repair Promise.

Circular by Design

When you’re ready to part ways with your ADKN piece, send it back. We’ll repair, repurpose, donate or responsibly recycle it - and you’ll receive store credit toward something new. Because true sustainability means keeping garments in use and out of landfill. The end of one piece can be the start of another. Learn more about Re.ADKN, our Circular Fashion Program.
