Selvedge denim
Selvedge denim is denim woven on a traditional shuttle loom, recognisable by the clean, self-finished edge the loom leaves on each side of the cloth. In our handling, it is the single word most often printed on a Japanese jeans label, and the first thing a collector checks by turning up a cuff.
Definition
A selvedge, or selvage in American English, is the self-finished edge of a piece of fabric, which keeps it from unravelling and fraying without any hem or tape. In woven cloth, the selvedges run parallel to the warp and are formed by the weft thread looping back at the end of each row. The word is a corruption of self-edge and has been in use since the sixteenth century.
Denim itself is a sturdy cotton warp-faced twill, usually with the warp dyed indigo and the weft left white, which is why jeans are mostly white inside. Most denim today is woven on shuttleless looms that make bolts sixty inches wide or more and leave cut, fringed edges. Some is still woven on the traditional shuttle loom, whose continuous weft reverses at each edge and leaves the selvedge.
Origin
Denim takes its name from serge de Nimes, and as cloth for trousers it rose in the United States after 1873, when Jacob Davis made the first rivet-reinforced denim trousers and moved production to Levi Strauss and Co. For most of the twentieth century American jeans were woven on shuttle looms, and the selvedge was simply how denim came. The selvedge was traditionally marked with contrasting warp threads, a coloured line that could identify a mill or a customer.
As mills moved to faster, wider shuttleless looms, the selvedge became a sign of the old method. Quality denim can be made on either loom, but selvedge denim has come to be associated with premium products, because showing the edge on a finished garment takes more care. In our reading, Japanese makers, notably around Okayama and in Osaka, have done more than anyone to keep the shuttle loom at the centre of modern jeans.
Key facts
| Meaning | Self-edge; in use since the sixteenth century |
|---|---|
| Loom | Traditional shuttle loom |
| Edge marker | Contrasting warp threads, often a coloured line |
| Cloth | Cotton warp-faced twill, indigo warp, white weft |
| Modern alternative | Shuttleless looms, 60 inches or wider, fringed edges |
How to identify it
- Turn up the cuff. A selvedge outseam shows the finished edge running down the inside of the leg, usually with a coloured line; an overlocked seam shows fringed, stitched edges.
- Read the line. In our handling, red is the familiar colour, but makers use many others; the colour alone does not prove a maker.
- Check the coin pocket. Many makers place the selvedge at the coin-pocket opening or the fly as well.
- Do not confuse with raw. Raw means unwashed; selvedge describes the loom. A pair can be either, both or neither.
- Vintage marks. On old American jeans, read the selvedge with the other details: the label, rivets and stitching. Our entry on amekaji sets the Japanese side of the story.
Where it appears in the collection
Selvedge sits on the denim shelf and the Evisu shelf. Examples include Levi's 501XX Big E selvedge jeans of the 1960s, a Levi's 507XX Type II jacket and Sugar Cane persimmon-dyed sashiko denim jeans. For the Japanese mills and makers, see our Kojima and Okayama selvedge guide and our guide to the Osaka Five.
