This piece in detail +

Good to know

  • Organic cotton and nothing else, rib-knitted: the dress follows your body while staying soft on your skin.
  • It slips on in one go, with no fastening to deal with: the row of buttons is there just for looks.
  • Covering on the legs, light on the arms: a dress you wear on its own, with nothing to adjust.

Material & feel

Rib knit means fine raised ridges that give the fabric bounce: it stretches as you move instead of pulling. The organic cotton makes it soft and comfortable from the first wear, no breaking in needed. Knitted in Portugal, it has real structure without being too warm.

When to wear it?

From May to September, on its own as soon as it's over 20 °C. For lunch on a terrace, a day sightseeing in town or a summer country wedding. In between seasons, under a light coat.

Fit & size

The rib moves with you: you can sit down, reach for a bag up high or lean over without feeling the fabric pull at the shoulders or waist.

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

Our commitments for this piece

  • 100% sustainable materials

    100% organic cotton.

  • Vegan

    No animal-derived materials.

  • Made in Portugal

  • Our brand

    Bonjour Demain is our own brand: clothes you'll want to keep for a long time, where material, durability, cut and comfort are designed together.

Our charter & our method

On our own pieces, we go further

Made in Europe, nowhere else

Our pieces are made in Portugal, in three workshops we chose one by one and visit regularly. The charter asks the brands we stock to tell us the names of their workshops; ours, we already know.

Traceable materials, chosen one by one

Not a supplier's catalogue: organic cotton, linen, Tencel and upcycled materials, chosen piece by piece to last.

The whole collection, not 75% of it

The charter requires the brands we stock to make 75% of their collection eco-friendly. On our own pieces, nothing is left out.

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.

Review summarybased on 12 reviews

This elegant, very comfortable dress wins people over with the exceptional quality of its durable cotton. Flattering fit and holds its shape well. Be aware: it runs large, so go for one size down. Ideal for every figure, although the neckline and length may need adjusting.

Make sure you follow the advice to size down and it's perfect! I thought I was just buying a simple black dress but it's "The little black dress"! So well cut and comfortable! The fabric is incomparable quality! I love it! Bonus: it hides my few extra pounds nicely. Really great brand ☺️
