Elegant movement in every step
The flowing maxi length creates a graceful sway when you walk, making your whole look feel more polished. It’s the kind of dress that does the work for you, even with simple accessories.

No tightness, no digging, no constant adjusting. Mariane is made to feel good from the first moment you put it on to the last photo of the night.
A timeless piece you’ll rewear
Trends come and go, but this silhouette stays. It’s the dress you’ll reach for again and again because it always feels appropriate, always looks refined, and never feels like “too much.”

The exact composition of this piece is listed in the product description above. To keep natural fibers beautiful:
- Wash wool, cashmere and knitwear by hand or on a gentle cycle at 30°C / 86°F, lay flat to dry.
- Refresh coats and suede by airing them out; use a soft brush for suede.
- Store knitwear folded, never on a hanger, to keep its shape.
