A tailored blazer dress that does the work of a great jacket and a dress at once: a deep V-neck, long sleeves, and a sharp button front. The Margaux is made for evenings out and more formal days.
Cut like a blazer and fitted through the body, it reads polished without trying. A deep V-neckline and button closure give it structure, while flap pockets add a functional, tailored detail. It sits above the knee, so it pairs easily with heels and simple accessories.
Key features

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.
