OS 02 Essence 2.0 Blueberry Performance Stretch Weave
Timo is 189 cm / 6'2 and wearing size L
Frequently bought together.
The OS 02 is an overshirt in a technical woven fabric, and the fabric is what makes it work. Structured enough to hold a clean line, easy enough to wear from morning to night. It sits between a shirt and a jacket: wear it buttoned up on its own, or open over a T-shirt or a knit. A regular fit, with two buttoned chest pockets.
The 2.0 is built on what people told us about our previous overshirt, with a reworked fit and an improved fabric. It is made from the same fabric as the TP 02 Essence 2.0, so wear the two together as a suit or split them up across the rest of the wardrobe.

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.

Ordering from outside the EU?
Outside the EU (except the UK), you don’t pay Dutch VAT: the 21% comes off your order automatically at checkout, as soon as you enter your address or switch country or currency. Import duties and local taxes aren’t included; the carrier collects them on delivery (DDU). We can’t calculate or cover them in advance, so check with your local customs office what to expect.
Questions about shipping? Our customer service is happy to help.

Good to know
- Send your items back clean and unworn, with their tags and packaging. That way we can process them quickly.
- Underwear can only be returned with the seal intact.

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.
