Environmental & social sustainability are at the heart of ReJean Denim.

We are committed to keeping unwanted clothing out of landfill. Creating luxury workwear pieces for our wide ranging customer. We believe denim is timeless and we endeavour to create pieces that work for everyone, regardless of their size, age, colour or gender.

ReJean Denim jackets and accessories are designed and produced in The Barras in the East End of Glasgow by our founder Siobhan. We source our denim from within the UK, mostly Scotland, keeping our carbon footprint to a minimum and supporting local businesses when purchasing hardware and habedashery. ReJean Denim collections are made with discarded denim transformed into timeless, hardwearing sophisticated and unique designs, where the material has ZERO impact on the environment. We take any leftover pieces and either use them to create a patchwork pieces that become the defining details of our bags and accessories or collaborative projects. We also run a repair service, and regularly donate anything further leftover the schools, universities and craft groups when they need it.



We create everything as a one-off piece, meaning you can literally have your jacket made up to your exact measurements. Meaning clothing that fits YOU.

At ReJean Denim, we believe that making conscious choices and being entirely transparent with the supply chain, is of the utmost importance to give our client a sustainable alternative and an extra reason to choose clothing that is fairly produced with the absolute minimum environmental impact. 

Other than washing our jeans and electricity to run our machinery ReJean Denim is carbon neutral. We use recycled brown paper packaging to ship our orders via Royal Mail or Parcelforce.




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


The jeans we use are discarded pieces, so as a matter of course (and hygiene) they need washing. We have in-house washing and dry facility that only uses 7 litres of water used per pair, where to create a brand new pair would use 7000 litres – this is more than the amount of water ONE person drinks over 13 years. 


Once the denim is washed and dried, Siobhan starts to sort denim into sets of 3 or 4 colours. These will then be taken apart  and put back together, recrafted into a one-off ReJean jacket. We use a scalpel and unpicker to take apart the jeans or trousers,  excess threads removed and fabric panels. Are pressed, ready to be cut into jackets.

Every jean used for our workwear jackets are selected and colour co-ordinated by hand by Siobhan and her team, ensuring every piece is quality checked and that they are happy with the gradient of colour way. 


We cut our jackets from a basic block pattern. Siobhan designs each piece as she goes. Responding to the details, washes and markings from the previous life of the denim. Taking inspiration from traditional French workwear but with a modern twist.

Each jacket is creatively cut and patched together, with hardwearing seam work that will last the test of time. We repurpose the belt loops from the jeans, stitching them on the Centre Back of the garment, just under the collar, (but on the outside) we think its a fun detail and a great way to reuse old pieces.


We purchase our hardware metal stud buttons from a local haberdasher, Fabric Bazaars. We are constantly inshore picking up bits and having a gab, so handy as they are literally a few minutes walk away from our studio.
Our buttonholes are stitched in-house on a refurbished Reece 101 chainstitch buttonhole machine. This beauty really take pride of place in our workroom.  Having this facility in-house saves us time and money and means we can also offer other makers access to this wonderful finishing service.

Our labels are manufactured  locally with Bar One clothing. They were produced in-house just a 10minute drive away from us. We place one label on the front pockets and one inside CB, underneath we hand number each jacket with a chainstitch.


Once our garments are labelled with buttons and buttonholes, we go over the jacket one last time checking for any worn ears and small holes from the scalpel. (usually left from cutting off the belt loops) We mend any areas by hand, usually visibly, adding fun unique details to each jacket.


Any scraps that are left are made into bags and accessories. We often use them in collaboration with other makers to create limited edition patchwork pieces.

We also run the ReJean Repair Shop, so we use our scrap denim to mend, patch and reinforce existing denim garments.

We do not bin any scraps and anything leftover is donated locally to schools and universities providing fabric for textile classes as and when they need it.
