This piece in detail +

Good to know

  • LENZING® ECOVERO® viscose, a wood-based fibre, soft and fluid on your skin.
  • A maxi dress that stays light: the fabric moves with you instead of weighing you down.
  • Buttoned all the way down: put it on and take it off without pulling it over your head.

Fabric & feel

ECOVERO® viscose is made from wood pulp: the fabric is smooth, cool to the touch and drapes softly. It absorbs moisture well, so you stay drier when it's hot. All along its length, it follows your steps instead of staying stiff.

When to wear it?

From May to September, as soon as the thermometer goes above 22 °C. At the office on hot days, in town, on holiday: wear it on its own from morning to evening.

Fit & size

The volume leaves your legs free: you can take long strides and sit down without the fabric pulling at the hips.

If you're between two sizes, we recommend you take the smaller one.

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

01

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.
  • When they manufacture in high-risk countries, we ask for additional guarantees and labels.
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.
