Latest Clothing Brands Data Reports

Nudie Jeans passes the fibre test, and that is rare for denim. Hold The Throne scanned all 527 live styles for plastic and synthetics, and 99.2% came back natural, mostly 100% organic cotton. The catch is in the ethics: a living wage gap Nudie admit is not closed, and cotton from India.
Pact markets itself as Earth’s Favorite organic cotton, but it is not a clean pass for sustainable clothing. Hold The Throne scanned all 205 of their live styles, and while 122 are 100% organic cotton, just over a third are blended with elastane, which is plastic.
Harvest & Mill sell legit sustainable clothing. I scanned all 74 of their live styles for plastic, synthetics and chemical fibre, and every single one is 100% organic cotton, grown and sewn in the USA, with no plastic, no synthetics, no chemically processed cellulose and no animal fibre.
Mate the Label calls itself plastic-free, but 42% of its range is spandex, elastane and lyocell. Here’s the product data that is available to download.

Sustainable Fashion, Ethical Brands and Insights

Ethical Consumer’s A to Z of ethical fashion brands gets the ethics right and the fibre wrong. Out of 29 picks, only Earthmonk and Where Does It Come From? are actually 100% plant fibre. The other 27 carry bamboo viscose, TENCEL, wool, elastane or mixed secondhand fibre.
I burned my whole swimwear business down to start again. At its peak doing five figures a month, Vivi Rufino and her partner David stopped producing entirely and spent seven years rebuilding Freedom Ecowear from polyester to natural fibres like hemp and organic cotton. Standing in the workshop the two of them built, Vivi explains why even recycled polyester failed, and why destruction was the only way forward.
Vogue’s 28 best sustainable clothing brands list is right about ethics and wrong about fibre. Of 28 brands, 26 fail a plant-fibre-only test because they lean on TENCEL, viscose, wool, silk and recycled polyester. Here is the proof, composition by composition.
She got expelled from school for sketching, and built a Caribbean sustainable swimwear brand. Vivi Rufino could not afford new clothes at college, took her sketches to her aunt’s sewing machine, and grew Freedom Ecowear into a beachwear label that now ships to over 30 countries, run with her partner David. I spent two days at Sol Luna Atelier with the two of them, and this is Vivi’s origin story in her own words.
