Design

Musubi means knot. Five of them run up the front of this jacket in place of a zip or a row of plain buttons — fabric loops over small domed buttons, the oldest closure there is. They take longer to do up and they are the entire reason the jacket looks like something rather than like a denim shirt.

Description

Take the hardware off a denim jacket and you find out whether the cut was any good. There is no zip here, no rivets, no metal shank buttons and no lapel — five fabric loops pass over five small domed buttons and that is the entire front. It is slower to fasten and it is the reason the jacket does not read as a denim shirt.

The collar stands straight with no fold, which keeps the vertical line unbroken from the neck down. Two patch pockets sit at the hip and the cuffs button. Nothing else has been added, because on a front this plain anything else would be the thing you notice.

The cloth is a washed denim at medium weight with a fine vertical slub through it, which is what keeps both colourways from looking flat. It is just under half cotton, blended with polyester for colour stability and viscose for softness, and there is no stretch in it at all — so the looseness you see is cut into the pattern rather than borrowed from the yarn.

A front with no hardware on it

A knot closure is cloth fastening cloth. A length of fabric is rolled and stitched into a loop on one side, and a small domed button sits opposite it; the loop passes over the button and that is the whole mechanism. It predates the metal button and it survived because it works, costs nothing but labour, and cannot rust, snap or jam.

On a denim jacket the effect is immediate. Strip out the zip, the rivets and the shank buttons and the front becomes a clean vertical line with five small interruptions on it. There is nothing shiny, nothing branded and nothing to catch the eye except the closure itself. It is slower to do up than a zip. That is the trade, and it is the right one here.

Stand collar, and why it matters

The collar stands straight up with no fold and no lapel. A lapel is a Western device: it exists to frame a shirt and tie, and it breaks the front of a garment into two diagonals. Remove it and the line runs unbroken from the neck to the hem, which is what lets a row of five small buttons carry the whole design.

It is also more practical than it looks. A stand collar closes at the throat without bunching, so the jacket blocks wind at the neck in a way a lapelled denim jacket never does.

The cloth, and what the blend is for

This is a washed denim at medium weight with a fine vertical slub running through it — visible as faint streaking in the blue and as texture under the surface in the black. That irregularity is what stops a flat garment looking flat, and it is the reason the black version reads as charcoal rather than as a dead black.

The composition is 47.3% cotton, 28.7% polyester and 24% viscose. Each part does something: cotton gives the denim its hand and the way it takes a wash, polyester holds the colour stable through repeated washing, and viscose takes the stiffness out. There is no elastane and therefore no stretch, which is worth knowing before you size. Everything roomy about this jacket is cut into the pattern rather than borrowed from the yarn.

Sizing a jacket with no give

Start with the Fits (kg) column, which is the maker's own guide and the fastest filter: 45-55kg at the smallest size rising to 95-105kg at the largest. Then check the chest, which runs 108cm to 126cm measured flat on the garment, and the shoulder, which runs 51cm to 60cm.

Because there is no stretch in the cloth, sizing down in the hope that it will give is the one mistake to avoid. The cut is already loose through the body, so your usual size in this chart will wear roomy by design. If you are between two, the larger one reads closer to how the jacket is drawn.

Wearing it, and which colour

It sits between a jacket and an overshirt, which makes it unusually useful. Over a tee in spring it is outerwear; under a coat in winter it is a mid layer; worn open it behaves like a shirt. Keep the trousers plain and the shoes low, and avoid pairing it with other denim unless the two washes are clearly different, because matching indigo rarely reads as deliberate.

The blue is the more obviously denim of the two, a mid indigo with the vertical streaking clearly visible and brass-toned buttons that stand out against it. The black is quieter and reads closer to a charcoal workwear jacket, with the same texture showing through at close range. The blue is the one to buy if you only buy one.

Answers

Questions, answered

What are knot buttons?

They are a closure made from the cloth itself: a loop of rolled fabric on one side that passes over a small domed button on the other. The technique is centuries old and predates the metal button entirely. They are slower to fasten than a zip and that is the trade — what you get is a front with no hardware on it, which is why the jacket reads as considered rather than as a denim shirt.

Which size should I order?

Use the Fits (kg) column in the chart first, which is the maker's own guide: 45-55kg at the smallest size up to 95-105kg at the largest. Then check the chest, which runs 108cm to 126cm measured flat on the garment. The cut is loose and there is no stretch in the cloth, so do not size down hoping it will give — it will not.

What is the fabric like?

A washed denim at medium weight with a fine vertical slub running through it, which is what gives both colourways their texture rather than looking flat. It is 47.3% cotton with polyester and viscose in the blend: the cotton gives the denim hand, the polyester keeps the colour stable through washing, and the viscose softens it. There is no elastane, so it has no stretch at all.

Blue or black?

The blue is a mid indigo with visible vertical streaking from the wash, and it is the one that reads most clearly as denim. The black is washed to a charcoal rather than a flat black, so the same slub texture shows through. Both have the same brass-toned buttons, which show more against the blue.

Is it a jacket or a shirt?

Both, which is the useful part. It is cut and weighted as a light jacket but it buttons like a shirt, so it works as an outer layer over a tee in spring and as an overshirt under a coat in winter. It is not insulated.

Does it have a lapel?

No. The collar stands straight up with no fold and no lapel, which is what keeps the front line unbroken and lets the row of knot buttons be the only thing happening on it.

What do I wear it with?

Keep the bottom half plain and the top half simple. A white or black tee underneath, straight or tapered trousers, low shoes. Avoid pairing it with other denim unless the washes are clearly different. Worn open it layers as easily as a shirt; fastened it reads much more formal than you would expect.

How do I wash it?

Use a neutral detergent, hand wash if you can, and machine wash cold if you cannot. Do not bleach. Dry in shade rather than direct sun, and keep it away from lighter colours for the first few washes — washed indigo gives up colour early.
