Fashion and Sustainability at ReJean


At ReJean Denim, sustainability is not an add-on or a buzzword, it's part of our DNA.

We are committed to being a zero-waste fashion brand by keeping unwanted clothing out of landfill, creating desirable workwear-inspired garments and accessories from 100% reclaimed fabrics. A refreshing antidote to fast fashion, we only release seasonless, small-batch capsule collections and made-to-order styles with a focus on timeless, gender-neutral investment pieces.

We never outsource to factories - our jackets and accessories are designed and produced in The Barras in Glasgow's East End by our founder Siobhan McKenna. We also source our denim and haberdashery solely in the UK, mostly from within Scotland, keeping our carbon footprint to a minimum and supporting local businesses.

Each ReJean collection is made with repurposed denim that has been previously discarded, which we rework
 into high quality, hard-wearing designs. Any scraps are reused to create patchwork details for our accessories, and we donate leftover textiles to schools, universities and craft groups to reimagine into new creative projects.

We also run a repair shop to breathe new life into old clothes, and we offer a range of alterations and custom measurements so you can treasure your ReJean piece forever.

Transparency is important to us. Here, we outline each step of our entire supply chain so you can be confident in your slow, sustainable denim investment.


We source our unwanted jeans from vintage warehouses around the UK. This allows us to work side-by-side with our suppliers to create our unique jackets and accessories, and keep our carbon emissions to a minimum.


The jeans we use are discarded pieces, so we take care to select the highest possible quality of textile, and ensure they are thoroughly cleaned. We have an in-house wash and dry facility that only uses 7 litres of water used per pair - brand new jeans use up to 7000 litres, more than the amount of water ONE person drinks over 13 years! 


Once the denim is washed and dried, we sort it into sets of 3-4 carefully coordinated colours, and start to deconstruct the jeans to develop the building blocks of each one-of-a-kind ReJean jacket. We use a scalpel and unpicker to take apart the jeans, snip away excess threads, press the fabric panels and prepare each piece for pattern cutting and reconstruction.


Siobhan designs each piece intuitively as she goes, responding to the details, washes and markings from the denim's previous life. Each jacket is creatively cut and patched together, with hard-wearing seam work that will stand the test of time. We also repurpose the jean belt loops and stitch them on the centre back of the garment under the collar.


We purchase our hardware, such as metal stud buttons, from Fabric Bazaar, a local haberdasher just a few minutes walk from our studio. Our buttonholes are stitched in-house on a refurbished Reece 101 chain stitch buttonhole machine, a beautiful vintage machine that takes pride of place in the workroom.  

Our labels are also manufactured locally by Bar One Clothing, located just a 10 minute drive away. We stitch one label on the front pocket and one inside the jacket, and underneath we label each unique jacket with a hand chain-stitched number.



Once our garments are labelled with buttons and buttonholes, we inspect the jacket one last time, checking for any imperfections and mending them by hand in a unique visible way.


We use recycled brown paper and craft tape to package each order, which ship by road via Royal Mail or Parcelforce.
