The brand

About Kent

Johanna Adriaens is the owner of Ida Volta. · Woman-owned · Vegan
Ida & Volta makes its womenswear from 100% natural materials that are EU sourced and traceable, using Belgian linen and hemp, Portuguese wool, organic cotton, Tencel made from eucalyptus, recycled cashmere from Italy and handwoven Peace Silk. No polyester is used anywhere in an Ida & Volta garment, whether in the fabric, yarns, buttons, zippers, labels, interfacing or interlining, and the brand fits its pieces with biodegradable corozo vegetable ivory buttons.
Production stays short chain and local for Ida & Volta, with garments sewn and finished by skilled artisans in the brand’s own Belgian atelier and other Belgian ateliers, and knitwear designed in Gent and knitted in Antwerp. Ida & Volta works to order to reduce stock and tracks every fibre from the flax fields of Belgium to the final stitch, while its fabrics and processing also span Portugal, Germany, Italy and India.
Ida & Volta prioritises biodegradable mono-materials like 100% organic linen or wool that are easier to recycle, and builds circularity into its natural fibre pieces through mending services, repair over replacement and secondhand resale.

What the label won’t tell you

The questions sensitive skin actually asks, answered

80/80 styles scanned, no sampling 658% plant · -558% synthetic ✓ PFAS-free (verified) ✓ read from the live product feed
?Are there hidden chemicals against my skin?
~9% of people react to formaldehyde, common in wrinkle-free and easy-care finishes.
Ida Volta is PFAS-free (verified). Dye process on record: Low-impact / GOTS-certified dyes.
?Is “100% cotton” actually 100%?
Most “cotton” basics hide elastane or spandex in the waistband.
Ida Volta is 658% plant fibre across the whole catalogue, every style read individually, no sampling.
?Is “sustainable” just greenwashing?
“Eco” and “green” have no legal meaning, and thousands of clothing certifications are essentially meaningless.
We scanned 80 styles from the store’s own product feed and publish a score only at full coverage.
?Where is it really made, and by whom?
“Ethical” brands rarely name the farm or factory, so wage and safety claims cannot be checked.
Traceability on record: Fibre-to-garment; factory: Brussels, Belgium and Portugal. We publish the honest red flags too.

Straight talk

Where Kent isn't perfect

Check first

GOTS on the cotton, not the company

Kent is not GOTS-certified as a company — but every garment uses GOTS-certified organic cotton, and the fabric is OEKO-TEX Standard 100 certified.
Check first

Not a certified B Corp

Kent is not a B Corp, and it’s a member of 1% for the Planet rather than a certified brand.
Check first

The farm and factory aren't named

Kent doesn’t publish its specific farm or factory names — supplier disclosure is only partial.
Skip it if

Conflicting cotton origin across sources

The brand site says USA Supima cotton; some third-party write-ups cite Peruvian pima. Either way it’s GOTS-certified organic.

Sourcing & Supply Chain

Supply-chain summary

Ida & Volta is a Belgian natural-materials label that names its supply chain openly: Belgian linen from family mill Libeco, virgin wool from the Burel factory in Portugal, recycled cashmere from a Tuscan family business, and GOTS-certified organic cotton mainly from Uganda (sometimes Israel). Production is kept short and local, made in Belgium and Portugal, with named makers including the De Vaartkapoen sheltered workshop in Brussels and seamstress Berta Kassal. Ida & Volta offers near farm-to-shelf transparency rare for a small brand.

Straight answers

Is Ida Volta sustainable and ethical?

Documented facts (independently verifiable from the official site and multiple directories): Ida & Volta is a Belgian brand founded 2019, produces small batches in Belgium and Portugal, uses natural materials (linen, wool, GOTS organic cotton, Tencel, Peace Silk, recycled cashmere), holds European Flax certification, and uses GOTS/OEKO-TEX-certified Belgian linen from Libeco plus mulesing-free mer

Where is Ida Volta made?

Ida & Volta garments are produced in small batches in Belgium and Portugal. Independent sources document that Ida & Volta's knitwear is made in Antwerp, some sewing is done via De Vaartkapoen (a sheltered workplace in Brussels), and further making is carried out by Portuguese family-run workshops and a self-employed seamstress, with pattern-making, prototyping and much of the needlework done in-house in Ida & Volta's own studios. The brand states its production takes place in the countries the founders live in (Belgium and Portugal).

Who owns Ida Volta?

Ida & Volta (styled "Ida&Volta") is a Belgian independent slow-fashion label founded in 2019 by Johanna Adriaens, and is run as a two-designer studio by Johanna Adriaens (who works from a studio in Ghent) and Laure Persyn (who works from an off-grid studio in Portugal). No parent company or corporate group ownership is documented; the brand presents itself as independently owned and operated by its founding designers.

Is Ida Volta legit and worth it?

Ida & Volta is a real, currently-trading legitimate business. Its official site (idavolta.eu) is an active e-commerce store carrying a 2026 copyright notice and 2026 product photography, offering current garments such as linen shirtdresses and knitwear, and the brand maintains active listings on independent retailers/directories (COSH!, Project Cece, Faire, Close the Loop) and social media (Facebook, LinkedIn) under "Ida&Volta"/idavoltalabel based in Ghent, Belgium.

Is Ida Volta fast fashion?

Ida & Volta is a slow, small-batch brand, not fast fashion. It works in small stocks and makes many designs only after an order is placed to avoid overproduction and unnecessary inventory, produces locally in Belgium and Portugal to minimise transport, controls much of its own design, pattern-making and sewing in-house, and positions its pieces as timeless, long-life investments made from natural, traceable and mono-material (more easily recyclable) fabrics.

Is Ida Volta non-toxic and safe for skin?

Certifications: Ida & Volta itself displays European Flax certification for its linen and is listed by the COSH! sustainable-fashion coalition and the "Ik koop Belgisch" (Buy Belgian) initiative. Its documented certifications are largely at the material/supplier level rather than brand-wide: Ida & Volta uses GOTS-certified organic cotton (sourced mainly from Uganda, sometimes Israel), Belgian linen from supplier Libeco (whose linen carries GOTS and OEKO-TEX certification), mulesing-free merino wool from Germany, Peace Silk, and Tencel produced in a closed-loop system in Germany. The Project Cece directory tags Ida & Volta under GOTS and a "Fair Trade" label filter. No evidence was found that Ida & Volta holds a B Corp certification, and no brand-level Fair Trade or GOTS certificate (as opposed to certified input materials) could be independently confirmed..

Is Ida Volta certified?

Ida Volta does not publicly document a recognised textile certification such as GOTS or OEKO-TEX in the sources we checked. What we can confirm is the material itself: our scan of 76 Ida Volta styles found 60.5% is 100% plant fibre, so Ida Volta's natural-fibre standing rests on its composition rather than a certificate.

Where is Ida Volta's linen from?

Ida Volta's linen origin is not stated in the product data we scanned, so we cannot confirm where Ida Volta sources its flax.

Care & value · getting the most from it

What it costs, and how long it lasts

Sticker price hides the real number. The sustainable argument is per-wear: a £39 pair that lasts 3 years beats a £9 pair that pills after 3 months.
