Do you know what you're putting next to your skin?
We choose our clothes by how they look. How they fit. How they make us feel. But we rarely ask about the most important thing: what exactly is in the material we wear directly on our skin all day long? During manufacturing, textiles go through dyeing, finishing and softening. A beautiful fabric may look perfect, yet the real quality is often hidden in what you cannot see.
Yet most of us have no way to check. With food we read the ingredients, with cosmetics we scan the list of substances — but with clothing we are usually left trusting how a garment looks and how a brand feels. And that is despite the fact that textiles stay against our skin for as much as sixteen hours a day.
That is why, with LADA garments, we don’t only address aesthetics, cut and functionality. We also address the health safety of materials. LADA garments carry the OEKO-TEX® STANDARD 100 certification. For the customer this means one simple but important thing: the material has been tested for harmful substances and is suitable for contact with the skin.
At a time when fashion often talks about sustainability, quality and responsibility, it is worth distinguishing between a nice story and a verifiable standard. OEKO-TEX® STANDARD 100 is not a fashion buzzword. It is a specific certification stating that the safety of textiles matters.
In the following sections we look at what the certification actually means, what is tested in a textile and why it is information that genuinely carries weight when choosing clothes.

What does OEKO-TEX STANDARD 100 mean and why does it matter for LADA garments?
One of the best-known and internationally recognised certifications in this field is OEKO-TEX® STANDARD 100. LADA garments carry it under the number PG020 209711. For the customer it is a clear signal that the material has been tested for harmful substances and meets the requirements for the health safety of textiles.
With the LADA brand there is one more distinction worth making. In the textile industry you often encounter the OEKO-TEX® STANDARD 100 certification on the material itself or on supplier fabric by the metre. LADA, however, communicates the certification on its end products – the finished garments. In the Czech market this is an exceptional standard, because the customer receives not just general information about the fabric, but a clearer signal that the health safety of the resulting garment as a whole is being addressed.
The OEKO-TEX® STANDARD 100 certification can be verified through the official OEKO-TEX® Label Check tool by entering the specific label or certificate number.

What is OEKO-TEX STANDARD 100?
OEKO-TEX® STANDARD 100 is a certification for textile products that have been tested for the presence of harmful substances. Simply put: if a garment carries this certification, it has passed a check according to defined criteria and meets the requirements for the health safety of textiles.
This is not just a marketing label such as „natural“, „gentle“ or „eco“. OEKO-TEX is a specific testing system focused on the safety of textiles for people. With garments this matters mainly because the material comes into direct contact with the skin.
What is checked during certification?
The OEKO-TEX STANDARD 100 certification addresses whether the textile contains harmful substances in amounts that could be problematic for human health. Checks include, for example:
- pH values,
- pesticide residues,
- preservatives,
- selected heavy metals,
- formaldehyde,
- problematic dyes,
- substances with allergenic or carcinogenic potential,
- other chemicals monitored in textile production.
Importantly, it is not only the fabric itself that is assessed. In a finished product, threads, dyes, prints, reinforcements or other parts of the garment can also play a role. That is precisely why OEKO-TEX STANDARD 100 is an understandable signal for the customer: this product has been tested for harmful substances.
Why does it matter?
Skin is the body’s largest organ. What we wear touches it directly and over long periods. With an everyday t-shirt, a dress or a base layer, it is not only about aesthetics. It is also about comfort, safety and trust in the material.
Certified materials make sense especially for people who:
- have more sensitive skin,
- care about material quality,
- do not want to wear textiles of unclear origin,
- are interested in sustainable fashion,
- want to buy less, but better,
- look for clothing with a considered origin and craftsmanship.

OEKO-TEX is not the same as „organic“
The OEKO-TEX STANDARD 100 certification does not automatically mean the material is organic or fully ecological. Above all, it means that the textile has been tested for harmful substances and meets the requirements for health safety. That is a difference.
The word „organic“ usually refers to the origin of the raw material or the way it is grown. OEKO-TEX mainly addresses the safety of the final textile product for people. And with clothing, that is essential.
Why does it matter for LADA materials?
Lada Vyvialová has long worked with materials that combine design, functionality, technology and a more sustainable approach to fashion. We design and sew our models also from functional fabrics with certified Czech nanotechnology and follow the principles of slow fashion.
For LADA garments, the OEKO-TEX STANDARD 100 certification is important information for the customer, because it confirms that the final products have been tested for health safety. This is significant especially for clothing that is not only beautiful at first sight, but is also meant to be comfortable, functional and safe to wear. Fashion, after all, is not only about how we look. It is also about what we put next to our skin.
Quality is not only visible. Quality shows in the details.
With a garment we often notice the cut, the material, the colour or the craftsmanship. Those are things we see immediately. Certification is less conspicuous. It is not a decoration or a trendy detail. It is proof that someone also addressed what the ordinary customer does not see at first glance. And that is exactly where its value lies.

Quality begins in the atelier – with material selection, cut and craftsmanship.
Sustainable fashion should not be only about a nice story. It should rest on concrete decisions: the choice of materials, the quality of craftsmanship, the garment’s durability and responsibility towards the person who wears it.
Who is clothing with OEKO-TEX certification for?
Essentially for anyone who does not want to choose clothing by looks alone. Certified materials will be appreciated especially by:
- women who wear a garment all day,
- customers with more sensitive skin,
- people who care about the origin and quality of the material,
- those who prefer slow fashion over fast fashion,
- customers who want fewer random purchases and more considered pieces in their wardrobe.
With the LADA brand, aesthetics meets functionality and responsibility. OEKO-TEX certification is one of the concrete proofs that the material matters. You can browse, for example, our dresses collection or the entire women’s collection.

How to recognise a quality garment?
A quality garment is not just one that looks good in a photo. A quality garment should:
- fit well,
- be comfortable to wear,
- withstand repeated use,
- be considered in both cut and material,
- have a clear origin,
- be safe for contact with the skin.
OEKO-TEX STANDARD 100 is one tool for navigating this better. It won’t tell you everything about a garment. But it tells you one important thing: the textile has been tested for harmful substances. And that is information that carries weight when choosing clothing.
Why are we talking about this?
Because customers have the right to know what they wear. At a time when the fashion market is full of fast collections, cheap materials and marketing shortcuts, it is good to stick to concrete facts. The OEKO-TEX STANDARD 100 certification is not a fashion buzzword. It is a verifiable standard that helps distinguish textiles tested for harmful substances from ordinary claims without proof. For LADA garments it is part of a broader approach: creating fashion that makes sense not only to look at, but also to wear every day.
Summary
OEKO-TEX STANDARD 100 means that a textile product has been tested for harmful substances and meets the requirements for health safety. With clothing this matters because we wear the material directly on our body. It is not an empty ecological claim and does not automatically mean organic material. But it does mean that the product has passed a check for substances that should not be in textiles.
And that is exactly why the OEKO-TEX certification is important information for LADA materials. Because beautiful clothing should not be only beautiful. It should also be considered, high-quality and safe for the person who wears it.
