This piece in detail +

Good to know

  • Light, soft fabric, comfortable to wear when it's hot.
  • Straight fit, midi length, with a side slit so you can move freely.
  • Boat neck that covers the shoulders well and hides the straps of a regular bra.

Fabric & feel

The blend of organic cotton and Tencel gives a supple fabric, light yet with good structure. The fabric is opaque, nothing shows through.

When to wear it?

This dress is perfect for summer. Wear it to the office with a pair of sandals or more simply at the weekend.

Fit & size

Straight fit that follows the lines of the body without clinging. It falls to mid-calf.

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.

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.
