£130.00 GBP
The True Cost of Sustainable Ethical Fashion

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

Made Slowly in London - Unlike fast fashion, which relies on assembly lines, your ADKN garment is crafted by a single artisan or a small team in London, using focused skill to cut, construct, and finish a premium quality ADKN item. We replace the speed of the assembly line with deliberate, technical precision:

  • Pyjama sets represent 2.5 to 6 hours of labour to master fluid drapes and hand-turned piping;
  • Dresses and Gowns require 3 to 8 hours of cutting, draping and precision stitching;
  • Outerwear is a technical marathon, taking 6 to 14 hours to hand-set storm flaps and bias-bound interiors.
  • In menswear, a Shirt or Jumper demands 1.25 to 5 hours to ensure sag-free necklines and interlined collars
  • Women’s Tops and Blouses receive 1.5 to 4 hours of slow-stitching for liquid movement
  • Finally, our Trousers and Skirts represent 3 to 6 hours of "hidden architecture," focusing on reinforced waistbands and precision-set zip flies.

We believe this time is essential for durability, ensuring your garment lasts years, not months.


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 masterclass in modern earth tones. The Forest Green Slate Jumper features a sophisticated dark green-grey hue that shifts beautifully in natural light. By combining a textured vertical-rib front, reminiscent of heritage knitwear, with a sleek zip-neck, this piece offers a distinctive look for the discerning dresser.

  • Textural Contrast: The vertical texture provides a flattering, structured look that elongates the frame while remaining soft to the touch.

  • Eco-Luxury Composition: Crafted with 70% Sustainably-sourced Viscose and 30% RPET (Recycled Polyester), transforming recycled materials into a high-performance, soft-touch textile.

  • The New Neutral: A more distinctive alternative to grey; pairs effortlessly with navy tailoring, charcoal denim, or tan chinos.
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.
