Full canvas, half canvas or fused — the single construction choice that decides whether a jacket moulds to you over years or bubbles and dies. How to tell which you are buying.
Between the outer cloth of a jacket and its lining lives an invisible third layer that almost no one asks about. It is the layer that decides everything — whether a jacket will mould itself to your body over the years or sag, bubble and surrender. There are two philosophies, and they could not be further apart: canvas, and glue.
What the canvas actually does
In a canvassed jacket, the structure comes from a chest-piece of woven horsehair and wool — a soft, springy interlining that is stitched, not glued, to the cloth. Because it floats freely between the layers, it behaves like a living thing. Body heat and wear slowly press it into the precise shape of your chest, shoulders and posture. A canvassed jacket does not start at its best. It earns its best. Three years in, it fits you the way a much-loved book falls open at a favourite page.
What fusing is, and why it exists
A fused jacket replaces that woven canvas with a sheet of interfacing bonded to the cloth by heat and adhesive — quite literally ironed on with glue. It is faster, cheaper and far easier to make at scale, which is why the overwhelming majority of jackets sold in the world are fused. When new, a good fused jacket can look crisp and clean. The problem is time. Glue is not cloth. It does not move as the wool moves, it does not breathe, and it does not forgive dry cleaning or humidity.
“Glue holds a shape for a season. Canvas remembers the woman who wore it.”

The word for what goes wrong
The failure has a name in the trade: bubbling, or delamination. When the adhesive bond breaks down — and in time it always does — the cloth and interfacing separate into small, permanent ripples across the lapel and chest. There is no pressing it out. The jacket is, quietly, finished. A canvassed jacket cannot bubble for the simple reason that there is no glue to fail.
The honest middle: half canvas
Between the two sits a sensible compromise. A half-canvassed jacket uses real floating canvas through the chest and lapels — the parts you see and that need to roll and drape — and fuses only the lower body, which is hidden and does less work. It costs less than full canvas, keeps the living roll of the lapel where it matters most, and is, for many women, exactly the right answer.
How to tell them apart in a shop
You can diagnose construction in ten seconds with your fingertips. This is the pinch test:
- Find the lower front of the jacket, between the bottom button and the hem, away from any pockets.
- Gently pinch the cloth and pull the outer face away from the lining, feeling for a loose, floating middle layer.
- Three distinct layers that move independently mean canvas — the inner layer floats free.
- Two layers stuck together as one stiff sheet mean fused — the interfacing is glued to the cloth.
- Then look at the lapel: a soft, living roll suggests canvas; a flat, board-like lapel often means glue.
Which one belongs in your wardrobe
There is no shame in fusing for a trend-led, single-season piece — it is honest engineering for a short life. But for the jacket you mean to keep, the navy blazer or the camel coat you will wear for a decade, canvas is not a luxury. It is the difference between a garment that ages and one that simply wears out. At the maison every tailored jacket is built on floating canvas, because we are not making clothes for one season. We are making heirlooms that happen to fit you now.
