An A-line trench cut loose and unlined, with a collar that falls soft rather than standing sharp. The Mathilde is the version you wear open, belt hanging, over a crop and a skirt.
The placket is double-breasted, the pockets are set in at the hip, and the hem swings out from the waist.
Key features
- Loose lapel collar — soft and wide, not stiffened.
- Double-breasted placket — two rows of buttons if you want it closed.
- Matching tie belt — in the same fabric, with loops at the waist.
- A-line cut — narrow at the shoulder and swinging out to the hem.

we love fashion
We buy dresses, knitwear, jackets and matching sets as one wardrobe rather than six separate categories. That's why the things you order months apart still go together.
