Sustainable Fashion FAQs, Answered by Pamuuc

What does sustainable fashion actually mean?

The honest answer is that it depends on who is defining it — and that is exactly the problem. For some brands, sustainable fashion means using recycled polyester. For others, it means carbon offsetting. For others still, it is a marketing posture with nothing concrete behind it.

For us at Pamuuc, it means making fewer pieces, choosing materials we can explain, producing close to our partners and saying clearly what we are still working to improve. A sustainability claim only carries weight when it connects to a specific material, a place, a partner, a certificate or a real production decision. Claims without that grounding are just noise.

What is greenwashing and how do you spot it?

Greenwashing is the practice of presenting a brand or product as more environmentally responsible than it actually is. It ranges from outright false claims to technically true but deliberately misleading ones — like calling a garment "made with sustainable fibres" when only 5% of the material is.

Some signs worth watching for: claims with no specifics attached, certifications mentioned without stating which product or batch they apply to, the word "eco" used without any explanation, and broad "carbon neutral" or "zero waste" statements with no methodology visible. The best antidote is looking for specificity. A brand that names materials, partners, locations and limits is doing the work. A brand that only uses adjectives usually is not.

What does OEKO-TEX certified mean?

OEKO-TEX is a set of independent testing and certification standards for textiles. The most widely known is OEKO-TEX Standard 100, which certifies that a textile product has been tested for harmful substances and found safe for human use. It covers dyes, finishing chemicals and a range of regulated substances.

When we mention OEKO-TEX at Pamuuc, we attach it to the specific dye, yarn or batch documentation it applies to. We do not use it as a general stamp for everything we make, because that would misrepresent how certification works. If a colour or delivery does not have confirmed documentation, we do not claim it does.

What does European Flax certified mean?

European Flax is a certification and traceability programme for linen fibre grown in Western Europe — primarily in France, Belgium and the Netherlands. It certifies that the flax has been grown without irrigation and without GMOs, using only rainwater, and that production meets European agricultural regulations. It also covers fibre quality traceability.

When we use linen sourced to this standard, we note it where the relevant batch documentation applies. Linen from this region has a long agricultural tradition, and European Flax certification is one of the more credible ways to support a claim about fibre origin and growing practice.

How does pre-order reduce overproduction?

Pre-order produces from confirmed demand rather than forecasted demand. In a conventional stock model, brands estimate how many units of each style, colour and size to produce before knowing whether customers want them. When the estimate is wrong — which it often is — the brand is left with unsold inventory that gets discounted, donated or destroyed.

At Pamuuc, customers order during the weekly window, the batch closes on Sunday at 23:59, and production starts the following Monday with confirmed quantities only. We do not cut fabric for pieces that have not been chosen. That does not eliminate all waste — logistics, packaging and occasional production rejects still create some — but it removes the largest source of overproduction by design.

Why do you use cotton and linen together?

Cotton and linen each have properties the other does not. Cotton is soft, familiar and easy to wear next to the skin. Linen is naturally breathable, has a distinctive texture and is stronger than cotton by weight. On its own, linen can feel stiff when new and prone to wrinkling. On its own, cotton can feel heavy and warm in summer.

A cotton-linen blend balances those qualities: you get breathability and lightness from the linen, and softness and ease of wear from the cotton. The result is a fabric that works well in shirts, dresses, trousers and shorts without feeling fragile or too casual. For warm-weather garments, the blend is one of the most practical choices available in natural fibres.

Is linen a good material for summer clothing?

Yes — linen is one of the oldest summer fibres precisely because of how it manages heat and moisture. It comes from the flax plant, has a naturally hollow fibre structure that allows air to circulate, and absorbs moisture without holding it against the skin. It also tends to feel cooler than cotton in direct sun.

Pure linen is known for wrinkling, which puts some people off. In a cotton-linen blend, the cotton component softens both the hand feel and the tendency to crease, making the fabric more practical for everyday wear. As a material choice for summer clothes, the blend is our answer to wanting linen's breathability without the maintenance.

Why does local production matter?

Local production gives a brand more visibility over quality, development and problem-solving. When a production partner is close by, you can discuss a fabric issue, review a sample or adjust a fit without a 10-day communication lag. That proximity makes it easier to catch problems early and improve each season.

It also means more accountability. A local partner is a relationship, not a contract. You know the people involved, you can visit, and you have shared context about how the work gets done. At Pamuuc, cut-and-sew work, labels, finishing and embroidery are handled through partners in the Barcelona area. Knitwear is made with Sompunt in L'Espluga Calba, Lleida. We prefer to name real places rather than use radius-based claims like "made in Europe" when we can be more specific.

Do more responsibly made clothes always cost more?

Usually, yes — and here is why. Smaller production batches do not benefit from the economies of scale that large fast-fashion orders do. Certified materials cost more than uncertified alternatives. Local or regional production is generally priced higher than production in lower-wage countries. When a garment accounts for all of those things honestly, the price reflects it.

The more useful question is not whether the price is lower, but whether the cost-per-wear is better. A garment that you wear 80 times before it wears out costs less per use than a cheaper garment you wear 10 times before discarding. That calculation is where better-made clothing becomes genuinely more economical, even if the upfront price is higher.

How long does a Pamuuc pre-order take?

Each weekly pre-order closes on Sunday at 23:59. Production starts the following Monday, and we estimate dispatch around 12 days after the weekly window closes. Once shipped, GLS delivery usually takes 2 to 5 business days across eligible EU destinations.

So from the moment you place your order to the moment the parcel arrives, the total time is typically between 14 and 20 days, depending on where in the weekly window you ordered and where you are located. Orders placed early in the week have slightly more wait time before the batch closes; orders placed on Friday or Saturday move into production sooner after cut-off.

Is sustainable fashion always slow fashion?

Not necessarily, but the two often go together. Slow fashion describes an approach to clothing that prioritises quality, longevity and thoughtfulness over speed and volume. Many sustainable brands work more slowly because their production methods — local manufacturing, small batches, certified materials — do not suit the pace of fast fashion.

At Pamuuc, our weekly pre-order model is a form of slow fashion by design. We are not trying to produce the maximum number of pieces in the shortest time. We are trying to produce the right number of pieces, made well, for people who have already decided they want them. That pace is intentional.

How should I care for cotton-linen garments?

Cotton-linen blends wash well, but they need a little care to stay looking and feeling their best. Here is what we recommend:

• Wash at 30°C on a gentle cycle, ideally inside out.
• Use a mild detergent without bleach or optical brighteners.
• Avoid tumble drying if possible — air drying keeps the fabric softer and extends garment life.
• If you prefer a crisper finish, press while slightly damp. Linen responds well to a warm iron on the reverse side.
• Store folded rather than hung to avoid the garment stretching on the hanger.

Good care is not just about keeping a piece looking nice. It is one of the most effective things you can do to extend how long you wear a garment — which is where the real environmental benefit lies.

How transparent is Pamuuc about its supply chain?

We explain the main production logic, the materials we use and the partners involved where we are able to. We name our knitwear partner (Sompunt in L'Espluga Calba, Lleida) and describe the production network in the Barcelona area for our cut-and-sew work. We explain which certifications apply to which materials and avoid using certificates as blanket claims.

We are still improving. Traceability at the fibre and yarn level, energy use in finishing processes, and packaging impact are all areas we are working to document more completely. We prefer to be honest about where the project stands today than to present a polished picture that is not quite true.

How do I know if a brand's sustainability claims are real?

Look for specificity. Real claims name materials, partners, locations, certifications and limits. They explain what the certificate covers, not just that it exists. They say which batch or product a standard applies to. They acknowledge what is not yet solved.

Vague claims — "we care about the planet", "responsible production", "mindful materials" — say nothing verifiable. Ask the brand: who makes this? Where? What does that certification cover? What are you still working on? A brand with honest answers to those questions has done the work. A brand that responds with more adjectives has not.

What are three practical ways to buy better clothes?

1. Buy fewer pieces with a clear use. Before ordering, ask whether you can imagine wearing this piece at least 30 times in the next two years. If yes, that is a solid reason to buy it. If not, it is worth pausing.
2. Care well for what you already own. Washing gently, drying carefully and repairing small issues extends garment life significantly. A garment that lasts twice as long has roughly half the impact of one that wears out quickly.
3. Look for proof, not positioning. Materials, partners, locations and limits say more than tone of voice. A brand that names things specifically is generally doing more than one that speaks only in values.
