This piece in detail +

Good to know

  • 100% organic cotton and nothing else: an easy-going shirt with the honest feel of cotton.
  • A shirt that makes the outfit on its own: no accessories needed to look sharp.
  • Wear it buttoned up or open like a light overshirt, and it changes role as your day goes on.

Material & feel

An organic cotton canvas with no added fibres. Despite the ecru background, the fabric stays opaque: you can wear it buttoned up without anything showing through. Pure cotton develops a patina wash after wash and keeps a natural feel.

When to wear it?

From May to September, when it's too hot for long sleeves. At the weekend, on holiday, on a terrace, and worn open as a light layer when the evening cools down.

Fit & size

It hangs straight without sticking to your back when it's hot, and leaves your shoulders free to move.

We recommend you take your usual size.

Our charter & our method

Our method

01

We seek out

We look for brands whose approach actually holds up, not the ones with the best marketing.

02

We analyse

We ask for workshop names, compositions and labels, along with the proof to back them up.

03

We validate

Without proof, a brand doesn't make it into our catalogue. It's the one rule that's non-negotiable.

Our selection charter · 3 pillars

Respect for people

  • All brands share the names of their partner workshops with us.
  • All of them commit to respecting the fundamental principles of the International Labour Organization.

02

Care for the planet

  • 100% of the clothes we select are made from at least 90% organic, vegan, recycled or natural materials.
  • All brands give us proof, with labels and certifications: GOTS, OCS, Oeko-Tex, Bluesign…
03

Integrity and values

  • At least 75% of collections must be eco-friendly.
  • All of them commit to always doing better, never worse just to produce more.
