This piece in detail +

Good to know

  • GOTS certified organic cotton and nothing else: soft and itch-free, even worn next to the skin.
  • A polished look with all the comfort of a Sunday jumper.
  • Roomy through the chest and arms: you move freely, nothing pulls.

Material & feel

A soft, smooth cotton knit that doesn't scratch like wool. Cotton lets air through: you stay warm without sweating as soon as you walk into a heated room. It washes at 30 °C, no fuss, no dry cleaner.

When to wear it?

In spring and autumn, when it's between 12 and 18 °C. On summer evenings by the sea, when the wind picks up. In an office where the air con blows hard.

Fit & size

The loose sleeves leave your arms free to drive, carry a bag or reach up. Its length doesn't bunch at the waist when you sit down.

Runs slightly large. If you're often between two sizes, take the smaller one.

Our charter & our method

Our method

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.

We validate

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

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.
