OS 03 Twill Black Washed Cotton Twill
Timo is 189 cm / 6'2 and wearing size M
Frequently bought together.
The OS 03 is our overshirt, inspired by workwear and built to double as everyday layering. Structured fabric. Easy everywhere else. It carries its own weight without any bulk. Wear it open over a tee on a mild day, or buttoned up once the weather turns. Either way, it does the work of a shirt and a jacket at once.
- Washed for a soft, broken-in feel from the first wear.
- Dyed after weaving for a deep, even colour that holds through every wash.
- Mid-weight fabric at 260 g/m2.
- Button-up front closure with a clean folded collar.
- Two front patch pockets in a clean chore construction.
- Regular fit with room to layer over a tee.
- Composition: 97% Cotton, 3% Elastane.
- The ETQ signature square at the back of the neck.
- Seasonless design suitable for every occasion.
- Made in Turkey. Designed in the Netherlands.
- Machine wash at 30°C, inside out and on a gentle cycle. That is all it needs to keep its shape and colour.
- From the collections Menswear and Overshirts

Shop the look
Made by specialists.
No single factory does everything well. So we don't ask one to. Every piece is built by the maker who masters that exact craft — the cut, the cloth, the finish. Chosen for skill, never convenience. It shows in how it's made, and in how long it lasts.
Sharp, never stiff.
The ease of your softest loungewear, with the line of real tailoring. The kind of comfort you stop noticing — on a silhouette that still reads refined.
Product design, not fashion.
From our Dutch studio we don't reinvent each season. We refine. The same icons, made better every time — the wardrobe you keep, not the trend you replace.

How it's made - Menswear
All ETQ garments are crafted in family-owned ateliers.
We team up with ateliers that work with traditional methods. Cutting, crafting, and stitching piece by piece with ultimate care. Unlike fast fashion companies, we have the luxury to take our time. Slow motion. We are masters of precision engineering.
Endless Comfort - Menswear
You look sophisticated, yet feel like Sunday mornings.
When it comes to materials, our bar is high. Only the finest materials enter the Atelier. No shortcuts. ETQs premium weaves and knits are smooth like butter. They are durable and have recovery properties. They stay in shape. And so will you.
Quality matters. We focus on things, that even the eye can't see. Obsessive, yes. But: soon after wearing ETQ you will notice the quality difference.
Dutch Design
Strong silhouettes. Nuanced colors. Thick layers of quality and a thin layer of logos. That’s ETQ. We master precision engineering and tinker with our products as if they were race cars. Every collection is the same but evolved. Continuously.
And so our story goes on. Evolving classic etiquette to match the pace of today. We don’t just do it. We do it with grace.

How to measure
Let’s find your perfect fit. Place a sheet of paper on the floor against the wall and put your feet (with socks) on it, heels against the wall. Make sure you lean on your feet with full power when measuring. Now you simply draw a line at the end of the biggest foot. Measure the distance with a ruler and find the size that matches it: see size table. Are you in between sizes? In that case, we suggest taking the bigger size.
