Buying guide
Almost every wardrobe is mostly vegan already. The difficulty is concentrated in four materials, and that is where the checking belongs.
Cotton, linen, hemp, viscose and polyester are all animal-free, which means most clothing qualifies without anyone trying. Vegan clothing brands earn the description by what they do in the remaining categories (knitwear, outerwear, insulation and anything with a shine) because wool, silk, down and leather trim are where the substitutions get difficult and where the marketing gets loudest.
Wool is the hardest to replace, because nothing animal-free matches its combination of warmth when damp, elasticity and odour resistance. The usual substitutions are organic cotton knits (warm but heavy and slow to dry), recycled acrylic (warm, light, sheds microfibres) and TENCEL blends (soft, poor at insulating). Recycled wool sits in an awkward middle: far lower impact than new wool, and still not vegan.
Silk is replaced most convincingly by cupro, a regenerated cellulose fibre made from cotton linter (the short fuzz left on the seed after ginning), and by lyocell in fine weaves. Both drape well. Neither has silk's strength, so seams take more strain.
Down is the substitution that has worked best. Recycled polyester insulation now performs close to down in everything except compressibility, and unlike down it keeps insulating when soaked. This is the one category where the vegan option is arguably the better product.
Trim. The overlooked one. Leather patches on jeans, horn or shell buttons, silk labels, wool-blend interlinings, and the bone-derived glue in some footwear. A garment can be cotton throughout and still not qualify because of a two-centimetre patch above the back pocket.
Paris, founded 2013 by Mats Rombaut, and 100% vegan by its own statement across footwear, apparel and accessories: the least ambiguous position of any label on this page. Its material work extends to cactus-based leather and an algae-resin sneaker foam.
A label whose environmental position is unusually broad, covering renewable energy, transport, permaculture, waste management, natural wines and plant-based nutrition as a single set of commitments rather than a materials policy alone. Its clothing has centred on hemp and organic cotton, alongside an interest in mycelium that ran into objects as well as garments.
Beaumont Organic — British-designed, produced in Europe, working in GOTS certified organic cotton, linen and lyocell. That fibre list is animal-free by construction, which makes the range easy to shop for this purpose even though the brand does not market itself as vegan. beaumontorganic.com
Komodo has been trading since 1988, which is a long time to hold an ethical position, with a broad organic and sustainable range across menswear and womenswear. komodo.co.uk
Nudie Jeans works in 100% organic cotton denim built around free repairs, which puts it in this guide for a different reason: the most animal-free thing you can do with a garment is keep the one you have. nudiejeans.com
Lucy & Yak states organic cotton, recycled wool and recycled polyester. It is independent and employee-owned, and not vegan as a brand, precisely because of that middle item. Many individual pieces are animal-free. lucyandyak.com
ARMEDANGELS works in organic cotton and recycled materials with a stated aim of garments that last, and publishes an annual impact report. It also uses wool in knitwear, so the brand does not qualify while much of the range does. armedangels.com
Neither of these is a criticism. It is the difference between a brand-level claim and a garment-level one, and reading it correctly is the entire skill this page is about.
Vegan describes an absence. It says nothing about whether the material is plastic, how much water the crop drank, what the dye did to a river, or who was paid what to sew it. A polyester dress made in a factory with no safety inspection is vegan. So is a PVC jacket. The word is genuinely useful, because animal welfare and tannery chemistry are real reasons to avoid animal materials, and it is genuinely incomplete, and the gap between those two facts is where greenwashing lives.
The workable approach is to treat vegan as one filter among several rather than a verdict. Read the composition; a plant fibre and a synthetic are both animal-free and behave nothing alike. Check the trim, because that is where an otherwise qualifying garment fails. Ask where it was sewn, which vegan says nothing about. And apply the same longevity test as everywhere else: the number of times a garment is worn does more for its footprint than the fibre it is made from.
Footwear is the category where the material questions are hardest, and it has its own guide to vegan shoe brands. The five checks that apply to any label, vegan or not, are in the slow fashion guide.
Questions
Yes. Cotton, linen, hemp, viscose and polyester are all animal-free, so most of a typical wardrobe qualifies without anyone trying. The difficulty is concentrated in knitwear, outerwear, insulation and anything with a shine.
Nothing matches it completely. Organic cotton knits are warm but heavy and slow to dry; recycled acrylic is warm and light but sheds microfibres; TENCEL blends are soft and poor at insulating.
Recycled wool has a far lower impact than new wool and is still not vegan.
No. A brand with recycled wool anywhere in its range is not a vegan brand, however many animal-free pieces it sells. Both can be worth buying, but only one can honestly carry the word, and the distinction is regularly blurred.
In the trim. Leather patches on jeans, horn or shell buttons, silk labels, wool-blend interlinings, and bone-derived glue in some footwear. A garment can be cotton throughout and still fail because of a two-centimetre patch above the back pocket.
