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.
