Sustainable clothing is easiest to judge by two things: what a garment is made from, and who has checked the claim. This Journal piece introduces the makers behind our Sustainable Corner and attributes every fact, either to the brand itself or to an independent register. Facts were last checked on 8 October 2026.
What does sustainable clothing mean at Fashion Roots?
At Fashion Roots, sustainable clothing means a maker with a named fact behind its claim, such as a fibre or a certification. We describe what each brand does and attribute every statement to its source. That standard applies to every maker below, and where a fact comes from the brand alone, the text says so.
JIORO: printed womenswear made in Europe
JIORO is a womenswear label founded in 2013 by designer George (Jioro) Dragnev, according to its Fashion Roots brand profile. The company is based in Sofia, with a showroom in Milan, and it is known for its own prints.
The same profile says the collections use organic cotton and natural viscose, alongside linen and silk blends, and that pieces are made in Europe by skilled craftspeople. The range is wide, and so are its fibres. Lyocell, modal and velvet sit beside them, and some pieces include polyester or other synthetics. The composition label on each product page shows which is which.
Lora Gene: a certified B Corp producing in Bulgaria
Lora Gene is a London label founded by Lora Nikolaeva, and its company, Gene Style Ltd, is a Certified B Corporation. B Lab's public register lists the certification as held since August 2020.
The register also records the overall B Impact Score: 97.9 in the current listing, against 81.5 in 2020. A company needs 80 to qualify, and B Lab gives 50.9 as the median for ordinary businesses that take the assessment. Certified companies repeat the verification every three years.
Read the certificate for what it is. B Lab's own legal notice says the criteria are its own and that no government or international authority has endorsed them. It is a private, third-party scheme with a published score, which gives a shopper more to check than a brand's description of itself.
Production is the brand's own account. Lora Gene says it works in Bulgaria across five factories and four workshops, with around 750 people behind its pieces. It says it visits those sites about every three months, that it has worked with most of them for over five years, and that they are audited independently three times a year.
Materials follow the same pattern. The brand says almost 98 percent of what it uses is natural, that more than half the range is pure silk and that its natural fabrics come mainly from surplus stock. It names England and France for silk, Italy for wool and cotton, and Bulgaria for linen. It also says about 90 percent of the range is made to order, which leaves almost no surplus stock.
These figures are the brand's statements, and we have not audited them. The B Corp listing is the independent part.
At Fashion Roots, the Lora Gene collection spans shirts, trousers, knitwear and silk dresses.
Yvonne Prive: dresses and coats
Yvonne Prive is a label whose pieces at Fashion Roots include dresses and coats, and its collection held 62 products as of 8 October 2026. Every piece is sourced directly from the brand or its official distributors.
The brand page states no fibres, place of production or certification, so we make no sustainability claim for Yvonne Prive here. The composition label on each piece is where to check what it is made from.
How do you read a sustainability claim on a label?
Ask who made the claim and whether it names something you can check. A certificate names a body and a date. A fibre claim names a percentage, a sourcing claim names a country or a mill, and a production claim names a number of sites.
Lora Gene's B Lab entry is the first kind. Its Bulgarian production figures and Italian wool are the others, with the brand as the only witness. Yvonne Prive's brand page names none of these, which is why this article makes no claim for it. JIORO's fibres are named on its profile, and the label on each piece completes the picture. Treat a claim with none of these as a mood, and move on.
What happens after purchase matters too. Washing less, repairing and storing well extend the life of any garment, and Lora Gene has a repairs page on its own site.
Key takeaways
- Judge sustainable clothing by named facts: a fibre, a place, a certificate or a number.
- Lora Gene's B Corp listing is independent. Its production and material figures are the brand's own.
- JIORO's range mixes natural fibres, lyocell, modal and some synthetics, so read the composition label.
- B Corps repeat verification every three years, so check the date on the register.
- Yvonne Prive's brand page states no fibres or certification, so no claim is made for it. Check the label.
FAQ
What does B Corp certification mean for a clothing brand?
It means B Lab has verified the company's results on its B Impact Assessment, which covers governance, workers, community, environment and customers. A company needs at least 80 points to qualify. B Lab sets the criteria itself, and its notice states that no government authority has endorsed them, so treat certification as one useful signal.
How often does a B Corp have to renew its certification?
Every three years. B Lab says the assessment and verification process typically takes at least 12 months, and certified companies repeat it on a three-year cycle. The register shows the date a company was first certified and its latest score, so check the listing for current details before relying on it.
Why does the composition label matter on a piece from a sustainable brand?
A collection name describes a theme. The composition label lists every fibre by percentage, including blends, linings and trims. It is the part of a garment that settles what the piece is made from, so compare it with what the brand says about its materials before you decide.
Sustainable clothing earns its name through facts someone can check. The makers above give you those facts, and the label on each piece gives you the rest.
