Fashion Revolution Week 2020: What's In My Clothes?

I’m surprised more horror stories aren’t written about clothing. Maybe because it looks so benign, hanging there in neat rows in a shop, arriving on your doorstep carefully wrapped, or sitting inert in your wardrobe. Or maybe it’s because we don’t like to scratch at fashion’s shiny facade. As well as horrifying tales of garment worker exploitation, there’s the environmental destruction to think about. After all, have you ever really considered what’s in your clothes?



We all think of cotton as a traditional, natural fibre. But cotton’s dark history of human exploitation and misery also started to include ecocide in the mid 20th century as DDT was sprayed onto cotton crops to kill the bollworm. Rachel Carson chronicled the devastating effect on wildlife in her book Silent Spring in the early 60s. Cotton is also an incredibly thirsty crop, and attempts to divert rivers to irrigate large cotton fields in Uzbekistan have transformed the Aral Sea, once the world’s largest inland sea and a thriving location for nature, fishing and tourism, into little more than a salty dust bowl.



A fact that really shocked me is the amount of water it takes to make one cotton garment, so much so that I had to emblazon it on one of my works of wearable art - 2700 Litres. On this shirt, every sequin represents one litre of water. That figure includes water for irrigating the cotton, processing the fibre, dyeing and finishing the garment, but that’s a lot of water. XR Hammersmith and Fulham also illustrated this beautifully during their Boycott Fashion event in Lyric Square - with nine rainbow-coloured bathtubs. Unfortunately I don’t have room for nine bathtubs in my hallway, so it had to be something small but visually arresting instead. 





Since clothes started to be mass produced in the mid 19th Century, we haven’t managed to do a great job of dyeing them safely. Fortunately we’ve stopped using arsenic as a green dye, but research carried out by Greenpeace as part of their Detox Fashion campaign, published in 2012, showed that brands were using azo dyes that contain cancer-causing carcinogens. Other tests revealed nonylphenol ethoxylates or NPEs in water systems, which are widely used in cleaning and dyeing processes. These chemical compounds are toxic to aquatic life, persist in the environment and biomagnify. Commercial fabric dyes contain mercury, cadmium and lead, and in many textile manufacturing areas around the world, the rivers running past dye houses and tanneries are the only source of water for drinking and washing for local people. 

Stories of dangerous dyes from days past inspired this horror-themed blog post a while back, and the creation of an arsenic-victim Halloween costume. But it’s a horror story that persists to this day and affects millions of people worldwide. 




Polyester clothing now accounts for over 60% of garments made worldwide. What many of the owners of those garments might not know is that polyester is made from plastic, a product of the petrochemical industry. The carbon footprint of a piece of polyester clothing is more than twice that of a similar piece of cotton clothing. And polyester clothing is also creating a global water crisis of its own - microfibre pollution.

When we think of plastic in our oceans, we might be thinking of the images we’ve seen in Blue Planet 2 - plastic bottles and containers bobbing about, bags or fishing lines caught around sea birds and turtles, or the scraps of broken-down plastic in an unfortunate fish’s stomach. But there is another hidden problem - the microfibres that are shed from synthetic garments every time we wash them. Too small to be trapped by filter systems in water treatment plants, they end up in the oceans where they add to the plasticky soup being consumed by sea creatures and eventually, us too.




Again, the figures are mind-boggling, as emblazoned on my second piece, 700,000 Fibres. Individually, these microfibres are far too small to see. But when you start to think of the amount of polyester clothing each of us owns and how often we wash those clothes, it starts to become a global problem. Research by Friends of the Earth has shown that 83% of water contains microplastics. That includes bottled water and drinking water as well as rivers and oceans.



I wish I could tell you that there is a quick fix for all these problems - a perfect fabric with no environmental impact, a magical dye that leaves no chemical residue but is colourfast and never fades. Unfortunately we live in a complicated, messy world and there are no quick fixes. Sustainability-minded manufacturers are gradually starting to switch to fabrics, dyes and processing that have less of an impact on the environment, but once again we need to keep asking the big brands to change. If we all ask #whatsinmyclothes we’ll hopefully end up in a situation where no one has to worry if they are drinking the residue from some freshly-dyed fabric, or scraps of the yoga pants they washed a while back.

Refashioning project: dyeing a dress for Greenpeace and Fashion Revolution's MAKE SMTHNG Week

As part of a campaign to reduce overconsumption, Greenpeace and Fashion Revolution have joined forces for MAKE SMTHNG week; encouraging everyone to get their craft on rather than shopping for new things.

As well as sewing professionally, I also enjoy doing it as a hobby, but it does mean that personal projects get neglected if I feel like I need a break! There are other ways to refashion or upcycle your rarely-worn clothes if you just can't get on board with lots of time-consuming sewing, and this week's refashioning project is a great example - a home dyeing project to make a dress more wearable.



I found this vintage Escada dress on a secondhand shop sale rail a couple of years ago; it was in good condition apart from some missing buttons, but it was a pale lemon yellow and the shoulder pads were a little too much, even for me! 

I knew I was unlikely to wear a pale yellow dress (it's not a practical colour when you travel everywhere by tube and constantly worry about spilling coffee on yourself) but the dress was 100% silk so I was fairly confident I would be able to dye it at home. 




Dyeing is a great way to transform your clothes, but you need to be aware of a few basic rules before you start. 
  • Natural fabrics like cotton or silk dye best. It's really hard to dye polyester with the most readily-available home dye kits, so check the label on your clothes first.
  • Dyeing won't really cover up a pattern, and might not cover up a stain unless you dye the whole garment a much darker colour.
  • Bear in mind that although your garment may be made from a natural fibre, it might have been sewn using synthetic thread, so if the garment has any visible stitching this could retain its original colour. 

  • You also need to bear in mind that with home dyes, the original colour of your garment will affect the final result. The colours shown on dye pack illustrate the result of dyeing white fabric, throwing another colour into the mix will definitely have an effect on paler colours. If I had tried to dye my yellow dress navy blue, I probably would have got a reasonable result, but if I had tried for a pale blue, I would probably have ended up with a green! In the end, I chose green on purpose; I knew I wouldn't get the exact colour on the packet because the dress was yellow, but I wasn't going to end up with an unexpected clash. 






I used a Dylon hand dye, a deep bucket, a long-handled spoon (for stirring the dye bath) and some sturdy rubber gloves! I put some pvc oilcloth fabric down on the floor and wore old clothes; home dyeing shouldn't be too messy, but the dye can stain other clothes and furnishings, so it's better to be on the safe side.

Hand-dyeing is the best option for delicate fabrics, but it's also possible to dye fabric in the washing machine. I've had good results with machine dyes too, but I'd only use them for large garments or long pieces of fabric, as you have to run the washing machine several times so it uses a lot of water.



Follow the instructions on the packet (some dyes also need salt to "fix" to the fabric), and you should be fine, but here are my two top tips:

  • Make sure the garment is thoroughly washed (and still completely wet) when you place it in the dye bath (or washing machine)
  • If the packet tells you to stir the dye bath for what seems like an excessive amount of time, do as you're told! This will ensure an even, professional-looking finish. Make sure your dye bath is big enough to move the garment around without too much splashing!




Once the dress had been thoroughly rinsed and dried, I added some vintage buttons to replace the missing ones. You can see on the photo of the dress label that the overlocking on the seams was done with a synthetic thread, as it was still white, but fortunately no stitching was visible on the outside of the dress.



I'm looking forward to wearing this dress (finally!) now that it's a colour that suits me. If you're planning any dye projects, remember to dispose of the dye carefully afterwards. Seeing the warnings for harmful or irritant chemicals on home dye kits make me even more aware of how toxic certain elements of the fashion industry are to the planet, so it's worth choosing your dye (and method of dyeing) carefully to minimise your impact.
