    Fit: True to size

    Lightweight overshirt

    A beautiful overshirt made of comfortable fabric.

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.

See how it's made

Product design, not fashion.

From our Dutch studio we don’t reinvent each season. We refine. The same items, made better every time. The wardrobe you keep, not the trend you replace.

Questions about the OS 01 Essence

How does the OS 01 fit?

A relaxed overshirt with a slightly dropped shoulder and a slightly longer sleeve, made for layering over a T-shirt or knit. Take your usual size; between sizes, take the smaller one, which also gives a cleaner line.

What is the fabric like?

Mid-weight woven twill at 285 g/m²: 62% polyester, 34% viscose, 4% elastane. Dyed after weaving for a deep, even colour that holds through every wash.

How do I wash it?

How do returns work if it doesn't fit?

Open our return portal and choose your new size: it ships as soon as your return is on its way, and you don't need to place a new order. Prefer a different colour or model? Choose store credit and order again, or choose a refund. Costs per country are on our returns page.

Is there a warranty on my ETQ product?

Yes, manufacturing defects are covered by the statutory warranty. Something not right? Send us a photo and your order number and we’ll find a solution together. Normal wear and damage from use are not covered.

Do you have a store?

We don't have our own store: ETQ is online only. You order here and try everything on at home. If it isn't right, you can exchange or return it through our return portal.

Something not right? Tell us.

We’ll sort it out with you. And it goes back to the studio, so the next version is better.

  • We’re here for you

    Something not quite as you hoped? We’ll look at it together.
