No label, still good: two pairs of unbranded suede jeans
Suede trousers cut like five-pocket jeans turn up often in vintage, and many have no brand label at all. Here are two pairs from our shop in Japan, one tan and one grey-beige, read side by side from the parts that are always there: the panels, the pockets, the closure and the lining.
Short answer: on unbranded suede trousers, look at four things. Seams across the legs show the trousers were pieced from several skins. Jeans-style pockets and rivets show which pattern the maker copied. The closure (zip and snaps) and the lining show how much care went into the parts you do not see. Neither pair here can be dated from a label, so any date is a judgment.
The two pairs
1. The panels: pieced from several skins
Most leather trousers we handle are pieced together from several pieces of suede rather than cut in one long piece per leg, and both of these pairs are. Look at how straight and even those seams are, and whether the color and nap of the pieces match. On both pairs, the panels are a close match.
2. The pockets: which pattern was copied
Pair B follows the five-pocket jeans pattern closely, right down to the coin pocket and the rivets at the pocket corners. Rivets at pocket corners go back to the 1873 patent of Jacob Davis and Levi Strauss (Wikipedia: Jeans). Pair A keeps the jeans shape with front and back pockets, but its waist is different, as the next section shows.
3. The closure and the lining: the parts you do not see
Both pairs have a lining inside, so the suede does not rub directly against your legs. Pair A closes with a heavy metal zip and two snaps; Pair B with a zip and one snap. To us, the heavy metal zip and doubled snaps on Pair A say the maker expected them to be worn hard.
What we cannot tell you
Neither pair has a maker's label, a country label or a care label, so we cannot name the maker or the country. The tan pair has only a small tag inside the waistband printed with numbers (31), most likely a size; it names no maker. The decades in the captions are our shop's judgment from the cut, the hardware and the wear. They are not written on the trousers.
Condition, honestly
Pair A has wear at the inside of the left leg seam. Pair B has light lifting at some panel seams, an oil-like mark and fraying at the hems.
Both pairs are in our shop
We run a small vintage shop in Kawagoe, Japan (Old Pawn Notes and the shop are run by the same people). Pair A measures 72 cm at the waist and 85 cm inseam; Pair B, 64 cm and 82 cm. The shop page is in English; the detailed description is still in Japanese.
