The leather blazer
A leather blazer is a tailored jacket, single-breasted, with a notched lapel and a shape that comes from the cut rather than from hardware. It does the job of a wool blazer, over a shirt in the day and a knit in the evening, with the difference that leather makes.
Why lambskin
A blazer needs to drape, hold a lapel and move at the shoulder, which is what lambskin does. It is cut here in a weight that keeps the lapel sharp without making the jacket stiff. It is not a jacket for rain; it is a jacket for most other days.
Fit
Tailored means the shoulder seam sits at the shoulder and the body follows the waist. The blazer is longer than the cropped biker and ends at the hip. Buy the size that fits the shoulders; the body has some ease, the shoulders cannot be altered. The product page gives the size the model wears at her height.
Wearing it
Over a shirt, a fine knit or a dress; with trousers or a skirt; open or with the top button closed. It is the most versatile piece in the women's range and the one that goes from a working day to an evening without a change.
