Jeans get dated from the pocket, the rivets, and the paper or cloth ticket at the waist. They do not get dated from how soft the wash is. A fade is sun and laundry. A cut comes back into stores and gets called a decade it is not. How to read a vintage clothing label is the general habit: union labels, care labels, fiber rules, measurements. This note is the denim overlay on that habit, for three makers people mix up in the same bin. It is not the price page. Levi’s 501s already have one. Wrangler jeans have one. Lee does not need a cloned page to be told apart from those two at the rack.
If the labels only support a range, the title gets a range. A correctly dated pair with a blown crotch is still a study piece. Brands worth slowing down for is a filter, not a permission to skip the pocket.
The pocket before the wash
Turn the pair over before you fall in love with the fade. Three pocket stitches sort the rack.
The arcuate is Levi’s mark: two curves on the back pocket, like a bird or a pair of wings, stitched in the familiar orange-gold thread. The W is Wrangler’s, a letter stitched on the pocket. The lazy S is the Lee curve, one loose S rather than a W or a double arch. These are maker’s marks in thread. They are the fastest honest sort in bad light. They are not a year.
A missing stitch means the pocket was worn bald, the arc was a wartime omission, or you are holding a different model. You do not fill the stitch back in with a guess. You go to the patch and the ticket. Reproductions stitch the famous marks on new denim every season. The stitch gets you to the right brand article. The ticket tells you whether the pair is old.
Yellow-gold thread is common to all three and to a hundred other jeans. Thread color is not a brand. A printed fake arc that sits on top of the cloth like ink is not stitching. Look at the back of the pocket. Real arcuate stitching is thread.
Rivets
Rivets are the metal buttons at stress points, usually copper on the older workwear pairs. Look at the corners of the front pockets and the base of the fly. Then look at the back pockets.
Levi’s covered the back-pocket rivets starting in the late 1930s, a change collectors date to 1937, so the copper would not scratch a saddle. On those pairs the rivet is still there and the cloth hides the back of it. A fully exposed copper rivet on the back pocket is a clue of an earlier construction. It is a clue. A replaced rivet, a reproduction, and a repair with a hardware-store copper cap all exist. If the rivet looks newer than the cloth around it, say so. Do not call a year off one dot of metal.
Later jeans, including later Levi’s, often drop pocket rivets for bar tacks, the tight stitch that does the same job in thread. A bar tack is not a defect. It is a construction. It also is not, by itself, a modern pair. Read it with the ticket. Wrangler and Lee used rivets and bar tacks in different eras and models. The presence of a rivet gets written down. It does not outrank the tag.
The waist button is stamped on the back. Those numbers and letters are a factory clue on some Levi’s pairs, the same way a pocket stamp is. Photograph the back of the button. Do not decode it from memory in the aisle. A blank button is a blank button. A button that says a different brand from the pocket stitch means the waistband was altered or you have learned something important. Believe the disagreement. Do not average the two brands into one title.
Patches, tickets, and lot numbers
The leather patch, the woven label, and the paper ticket are the record. Levi’s older pairs carry a leather patch at the center back, the two-horse patch on the famous ones, and a printed or stamped ticket that can sit on that patch or inside the pocket. Wrangler’s cowboy cut often has its own leather patch and a model number on the ticket. Lee used a leather patch on older Riders and a twill or printed ticket. A patch that is cracked is still a patch. Read it before you moisturize it into mush. Conditioner that darkens a stamp is damage you did.
The lot or model number is the pair you actually have. A red tab does not mean 501. Levi’s made a lot of other numbers, including zip-fly jeans that are not the button-fly 501. Wrangler’s 13MWZ is a cowboy cut, and other Wrangler numbers are other cuts. Lee Riders are a line, not a synonym for every Lee garment. The number in the listing has to be the number on the ticket. If the ticket is gone, say the model is unidentified and sell the pocket stitch, the measurements, and the photos. Do not reconstruct 501 from a vibe.
Date codes hide in those stamps: a factory number and a date code whose format changed over the years. The formats are published by people who study them, and they are easy to misread by one digit. Photograph the stamp and match it later. A wrong year in a title is a return. An unidentified stamp is an honest listing. The clothing-label habit still applies to the care label sewn beside the ticket. In the United States a care label puts you in the era after those labels were required, not in a pre-war closet. This page will not repeat that rule. Use it, then come back to the denim.
Country of origin is a line on the same tag. A United States pair and a later import can both be real, and they are different searches. Do not crop the country line because a buyer you imagine only wants one of them.
Levi’s, past the tab
The red tab on the right back pocket is Levi’s. Lettering in all capitals, the big E, is the older tab. Levi’s changed that lettering to a lowercase e in 1971. That is a date clue with a year attached, and it is still one clue. A replaced tab, a missing tab, and a tab sewn onto a pocket that does not otherwise match are weaker. The 501 guide is where selvedge, the care label, the waist measurement, and the price decision already live. Use it for a pair that is actually a 501. Do not make this article a second copy of it.
Two Levi’s facts that are not on that price page as dates: the tab itself was introduced in the 1930s, and during the Second World War the arcuate was dropped to save thread. Some wartime pockets have a painted arc, or none. A missing arc can be those years. It can also be wear, or a later jean, or a pocket that was replaced. Painted arcs have been faked. If you are going to claim a war pair, you need the rest of the pair to agree: the rivets, the patch, the absence of a modern care label. One missing stitch is not a war.
Selvedge is the finished edge of the denim, visible when you turn the hem up. A red line in that edge is the classic Levi’s selvedge. The 501 page already says selvedge is not automatically a pre-1970 pair, because Levi’s sold selvedge again later. Believe that. A red line is an edge. The ticket is the year.
Wrangler
If the pocket says W, you are on the Wrangler page, not the 501 page. The denim check that belongs to Wrangler is broken twill: the diagonal of the weave reverses, so the leg does not twist the way a continuous right-hand twill can. Look at the inside of the cuff. A twill line that breaks direction is Wrangler’s cloth. Levi’s 501 denim is usually one continuous diagonal. The weave is a check, not a romance. It also will not date the pair by itself. A current Wrangler can be broken twill. The ticket and the patch do the dating. Blue Bell on an older patch or ticket is the company name Wrangler used, and it is a reason to slow down and read the whole label. The guide is the model number, the button, and the failure modes. This paragraph is only how you know you should open that guide.
Lee
A lazy S on the back pocket points at Lee. Older Lee Riders carry a leather patch and a ticket you can photograph. The wording on that ticket, including union marks and a care label if one exists, is the date range. This note will not print a Lee year chart. The charts that exist disagree in the details people actually argue about, and a memorized chart you only half remember is how a 1980s Rider becomes a 1950s Rider in a title. Photograph the ticket. Match it to a reference you can look at twice. If you will not do that, say Lee jeans, show the pocket and the tag, and do not invent a decade.
Lee also made work clothes that are not these jeans. A union-all or a jacket with a Lee label is a different garment. The pocket stitch rule is for the jeans in front of you. Do not export it to every garment in the closet that says Lee.
Measurements and the hem
Vintage sizes lie, and the label article already says to measure. Jeans version, short: flat waist, rise, thigh, and inseam, in inches, after you have washed them if you are the one who washed them. Shrinkage is your doing if you dried them hot. A chain-stitched hem, the looped stitch along the cuff of many Levi’s and Wrangler pairs, comes out if someone cut the jeans shorter. A cut hem with the selvedge gone is an altered pair. Collectors pay for unaltered. Wearers may not care. Name which sale you are running. The 501 guide’s alteration note is the price version of that fact.
Holes in the crotch, a split outseam, and a replaced zipper are condition. They happen to old jeans and to jeans that were worn hard for a short time. Do not use the hole as a substitute for a missing ticket. Do photograph the hole first.
What a photo can settle
A photo can settle the pocket stitch, both back pockets, the red tab lettering if the tab is flat and lit, the back of the waist button, the leather patch, the ticket, the care label, the country line, the hem edge, and the inside of the cuff for the twill. It cannot feel whether a rivet was replaced yesterday. It cannot measure a waist from a photo of someone sitting down. It cannot rebuild a date code you did not include.
Take those frames before you pay a decade premium. Then match the code with the pair in your hands, not with the pair you hope it is. Worth can read a clear Levi’s, Wrangler, or Lee mark off a ticket you put in frame. It cannot date a pair from a fade, and it cannot see a big E on a tab that is folded under. The thrifting page is the rack. The pocket is the sort. The ticket is the year. Sold listings of that ticket, that waist, and that hole are the price, after the fee you look up rather than remember.
