This piece in detail +

Good to know

  • Organic cotton and nothing else: a jumper dress that feels soft against your skin, vegan and made in Portugal.
  • Room at the shoulders and arms, and a neater line towards the hem that avoids a shapeless look.
  • The high neck keeps your neck warm, no scarf needed.

Material & feel

A soft, supple organic cotton knit that drapes without clinging. It stays comfortable all day, without the itch of wool. As you wear it, it adapts to your movements, and a wash brings back its original shape.

When to wear it?

From October to March, for full days in a heated office: cotton keeps you warm without making you sweat. In between seasons, wear it on its own as soon as the sun comes back, and under a coat when the cold bites.

Fit & size

You raise your arms, grab your bag, drive, without the shoulders pulling. Narrower at the bottom, it keeps a clean line when you sit down.

We strongly recommend you take one size down from your usual size. This piece runs large.

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.

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.

Review summarybased on 10 reviews

Elegant and comfortable, this dress wins people over with its soft fabric and perfect fit. The colours are beautiful, although it runs large. For an ideal fit, go for the size below or define your waist with a belt.

Top! Nice material, wear it with or without a belt. Take a size down, as is often the case with Jannjune

Really lovely dress, super comfortable, for everyday or an evening out. The green is a little lacking in brightness

Really pretty dress but runs very large! So it's better worn with a belt to cinch the waist

The fabric seems really good quality. The dress really runs large but with a belt it looks elegant
