How to Read Vintage Clothing Tags and Labels (A Complete, Honest Guide From Someone Who Does This Every Day)

I read clothing labels every single day. Not as a hobby, but as a practical necessity. Every piece that comes through Revaleur gets checked before it goes anywhere near the shop, and the label is almost always the first place I look. It tells me when something was made, where it came from, whether the brand claim stacks up and often whether the price being asked is reasonable. Once you know what to look for, a label stops being a small rectangle of fabric sewn into a seam and becomes something genuinely useful. This guide covers everything I have learned from handling hundreds of vintage Ralph Lauren, Tommy Hilfiger, Lacoste and similar pieces, written so you can use it practically, whether you are browsing a charity shop, buying online or just trying to date something you already own.

The golden rule before you start

Every label clue you find is a "not before" date, not an exact date. A garment with an RN number issued in 1964 could have been made in 1964 or in 1985. That same company kept using the same registration number for decades. So the rule is: treat each clue as setting a floor, not pinpointing a year. Then cross-reference at least two or three separate clues before you settle on an era. One clue alone is interesting. Three clues pointing to the same decade is confidence.

Care labels: the single most useful dating shortcut

If you learn nothing else from this article, learn this. In the United States, the Federal Trade Commission made care labels legally mandatory from July 1972. That means any American garment with no care label at all was almost certainly made before 1972. That is one of the most reliable single clues in vintage clothing, full stop.

But there is more nuance than just present or absent. The format of the care label also changed over time, and that evolution gives you a rough timeline to work with:

• No care label at all: Pre-1972 American production. Could be pre-1971 if the brand was early to comply.
• Written instructions only ("Machine wash warm, tumble dry low"): 1972 through to the mid-1990s. Early labels used plain English because the symbol system had not been adopted yet.
• Mixed written and symbol instructions: Broadly 1990s into the 2000s, as symbols were phased in gradually.
• Symbols only, no written words: Post-1997 in most markets, when the ASTM care symbol system became standard in the US. Europe and Japan moved to symbols earlier, from the late 1960s onward.
• Tagless neck print (care info screen-printed directly onto the collar lining): This does not appear before about 2002. If a garment has a tagless neck, it is not vintage in any meaningful sense.

A quick note on European garments: the care symbol system was adopted earlier in Europe, so the absence of symbols on a European label does not carry the same dating weight as it does for American pieces. For the Ralph Lauren, Tommy Hilfiger and Lacoste items I handle most often, always check both the brand label and the separate care label, as they sometimes come from different eras of the brand's production.

RN and WPL numbers: your secret weapon for dating American garments

This is the tool most casual vintage buyers do not know about, and it is genuinely powerful. American garments carry a Registered Number, shown as "RN" followed by digits, or sometimes a WPL (Wool Products Labeling) number for older wool items. These numbers were issued sequentially by the Federal Trade Commission, which means the number itself tells you something about when the brand registered.

Here is the rough timeline:

• WPL number, no RN number: The brand registered before 1959. WPL numbers ran from 00101 to 13669 between 1941 and 1959. If you see a WPL with no RN, you are most likely looking at something from the 1950s or earlier.
• Five-digit RN starting around 13670: The RN system began in 1959. Numbers between roughly 13670 and 50000 cluster in the 1960s to mid-1970s.
• Five-digit RN above 59000: Generally points to post-1970 registration.
• Six-digit RN above 100000: Indicates registration from the late 1990s onward.

The important caveat: the RN dates the company's registration, not the garment itself. A brand that registered in 1964 kept printing that same number on labels made in 1990. So a low RN tells you the garment cannot have been made before that registration date, but it does not confirm it was made right then. This is why you always cross-reference.

The really useful part is this: you can look up any RN number for free at rfrn.ftc.gov, the FTC's public database. Type in the number and you get the company name that held the registration. If that company no longer exists, or was absorbed into another brand during a known period, that narrows your window considerably. It takes about thirty seconds and it is one of the most underused tools in vintage buying.

Union labels: a goldmine for dating American vintage

Union labels are one of the most exciting things to find on a vintage garment, and not just for dating purposes. They are a piece of labour history sewn directly into the clothing. The most common you will encounter is the ILGWU label (International Ladies' Garment Workers' Union), usually small, square, and in red, white and blue. The ACWA (Amalgamated Clothing Workers of America) and later ACTWU labels appear on menswear.

The ILGWU label changed its design several times, and each design maps to a specific window:

• Large "AFL-CIO" affiliation, no registered trademark symbol: Broadly 1955 to 1963.
• Smaller AFL-CIO, with a registered trademark "R" symbol: 1964 to 1973.
• Red, white and blue design, "ILGWU" prominent: 1974 into the 1980s.
• No union label at all: By the 1990s, as American manufacturing declined, union labels became increasingly rare.

If you see "Union Made" or a union bug on a garment, that is a strong indicator of American domestic production. The presence of the label alone tells you the garment was made during the union's active years. The specific design tells you which part of that window you are in.

Country of origin: what it says and what it does not

The country of origin label is required by law in most markets and it changes meaningfully across decades. For American pieces, "Made in USA" is a strong vintage indicator, particularly for brands like Ralph Lauren and Tommy Hilfiger that moved significant production offshore during the 1990s and early 2000s. A Ralph Lauren piece marked "Made in USA" is almost certainly pre-mid-1990s. That matters for both dating and value.

Some country names on labels are themselves dating clues. "Made in West Germany" means pre-1990, when reunification happened. "Made in Yugoslavia" means pre-1992. "Colony of Hong Kong" means before 1983. "Made in Czechoslovakia" means pre-1993. These are not common finds on the brands I deal with, but they are worth knowing.

For the brands most relevant to Revaleur, the country of origin shift is particularly useful:

• Ralph Lauren "Made in USA": Generally pre-1995.
• Tommy Hilfiger "Made in USA": Very early pieces only, pre-1990s at the latest. Most 1990s Hilfiger is made in Asia.
• Lacoste "Made in France": Early to mid-production era. Later moved to Peru, then various countries. French-made Lacoste commands a premium and is genuinely older.

Fabric content: when it appeared and what it means

Fibre content labelling was not required by US law until 1960 (under the Textile Fiber Products Identification Act). So a garment with no fabric content information at all is almost certainly pre-1960. That is a powerful clue on its own.

The type of fabric listed also tells you something about era. Polyester blends became common from the late 1960s and were ubiquitous in the 1970s. If a label lists "65% Polyester, 35% Cotton" it is likely a 1970s piece. Pure cotton or pure wool labels without any synthetic content push toward the 1950s or early 1960s. From the 1980s onward, you start seeing more sophisticated blends and technical fabrics.

Label materials, fonts and construction: reading the physical object

The label itself is an artefact. Look at it as an object, not just as text. Here is what the physical characteristics tell you:

• Woven satin or rayon label with embroidered script font: Pre-1960s. Hand-guided embroidery on older labels has a slightly irregular quality that machine-made modern labels do not. Turn the label over: early woven labels show clear mirroring on the reverse. Computer-controlled looms from the 1980s onward produce a cleaner, tighter reverse.
• Woven label, sans-serif font, more standardised appearance: 1960s to 1980s. This is the era when mass production became dominant.
• Printed synthetic (almost paper-like) Tyvek-style care label: This style of care tag becomes common from the early 1970s and is characteristic of the 1970s and 1980s.
• Large, bold, brand-assertive woven label: From the 1980s onward, brands like Ralph Lauren, Tommy Hilfiger and Lacoste started using the interior label as a statement of identity, not just information. Big logos, multiple interior labels, branded hang tags. This is characteristic of the 1980s and 1990s.

Script and serif fonts generally suggest pre-1960s. Sans-serif, blocky fonts are more common post-1970. Bold, brand-logo-centric labels are very much a product of the 1980s and later.

Sizes on vintage labels: smaller numbers, different meanings

Vintage sizing runs significantly smaller than modern sizing. A size 14 from the 1950s fits more like a modern size 8 or 10. Always check the actual measurements if they are listed on the label, and do not assume a size number means what it would today.

Half sizes, shown as "16½" or "12½", indicate a garment made between roughly the 1940s and 1970s. They were designed for shorter, curvier figures and largely disappeared after the 1970s. Seeing a half size is a reliable early indicator.

Odd-numbered sizes (3, 5, 7, 9) look like today's juniors sizing but on older garments they were used for adult women's clothing. The modern "Junior" category only emerged in the early 1980s. So a pre-1980s garment with an odd-numbered size was made for an adult, not a teenager.

Brand-specific label evolution: Ralph Lauren, Tommy Hilfiger and Lacoste

This is where I can add something most generic guides cannot, because I handle these brands constantly. Each one has a label evolution that is specific enough to be genuinely useful for dating and authentication.

Ralph Lauren

Ralph Lauren launched in 1967, so nothing can claim to be Ralph Lauren from before that date. The earliest Polo by Ralph Lauren labels are simple: white embroidery on a navy background, just the brand name, no polo player logo, no elaborate crest. As the 1970s progressed, the iconic polo player silhouette became more prominent on labels.

By the 1980s, the label became more assertive, with the polo player in full prominence and "Polo by Ralph Lauren" in clear lettering. The 1990s brought the "Polo Sport" sub-label (blocky sans-serif font, athletic aesthetic) and the "Chaps Ralph Lauren" line. "Made in USA" on a Polo by Ralph Lauren label generally indicates pre-mid-1990s production. The "Hilfiger Athletic" equivalent for Ralph Lauren is Polo Sport: if you see it, you have a 1990s piece.

A key authentication point: the stitching on genuine vintage Ralph Lauren labels is consistent and tight. On fakes, the embroidery often looks uneven, the navy background is the wrong shade, or the font proportions are slightly off. The label should feel substantial, not thin or papery. If you want to go deeper on this, I have written a full guide on how to authenticate a vintage outerwear jacket that covers many of the same physical construction checks.

In terms of value: genuine early 1990s "Made in USA" Polo by Ralph Lauren pieces, particularly heavier cotton knits and outerwear, regularly sell for €60 to €180 in good condition. The label is a major part of what drives that price.

Tommy Hilfiger

Tommy Hilfiger launched his first signature collection in 1985, so nothing labelled Tommy Hilfiger can predate that. The classic red, white and blue flag logo became the defining visual from the late 1980s. Early flag labels from this period tend to be larger and more boldly placed inside the garment.

The "Hilfiger Athletic" sub-label, with its slanted logo variant, was used specifically during the 1990s and was discontinued in the early 2000s. If you see a Hilfiger Athletic label, you have a 1990s piece, full stop. The Tommy Jeans label from the same era is almost identical to the main Tommy Hilfiger neck tag except for the "Tommy Jeans" spellout.

In the early to mid-2000s, the neck tags evolved into longer strips with the flag logo acting as a visual break between "Tommy" and "Hilfiger." Tags from this era often used white for women's pieces and navy for men's. That format shift is a quick and reliable dating tool.

Good condition 1990s Tommy Hilfiger pieces, particularly the bolder logo items from the peak streetwear era, fetch €40 to €120 depending on the piece. Hoodies, heavy knits and outerwear from that decade sit toward the top of that range. I have written a full honest assessment of whether Tommy Hilfiger is worth buying secondhand if you want the full quality picture alongside the dating detail.

Lacoste

Lacoste is a slightly different challenge because the label evolution is less well documented in English-language guides. The crocodile logo itself has changed subtly over the decades. Earlier crocodiles (pre-1980s) have a slightly more detailed, hand-drawn quality to the embroidery. Post-1980s crocodiles are more standardised and uniform.

"Made in France" Lacoste is the holy grail for collectors: heavier fabric, better construction, genuine vintage status. These pieces turn up less frequently and command a premium, often €50 to €150 for a polo in excellent condition. Later production moved to Peru and then various other countries. The country of origin label is your first and most reliable clue with Lacoste.

Other label details worth checking

Address without a zip code

American zip codes were introduced in 1963. If a label includes a brand address without a zip code, the garment is pre-1963. This is a very specific and reliable clue for older American pieces.

Lot numbers

A "Lot" number on the brand tag, typically a letter or short number sequence, is characteristic of labels from before about 1980. You do not see them much on pieces made after that.

Woolmark logo

The Woolmark logo (the familiar spiral symbol) has gone through several versions. The original single-spiral "100% wool" version dates from 1964. A version indicating 60% wool content appeared from 1971. The 50% wool version came in from 1999. So if a garment carries the original Woolmark symbol and claims 100% wool, you know it is from 1964 or later but the design of the symbol still helps narrow the window.

A practical step-by-step process for dating any vintage garment

When I pick up a vintage piece, here is the actual order I check things. You can do exactly the same:

1. Is there a care label? Yes or no. No care label immediately suggests pre-1972. If present, is it symbols only, text only, or mixed? That tells you the broad era.
2. What does the care label say about fabric content? No fibre content listed pushes you toward pre-1960. Polyester blend suggests 1970s. Pure natural fibre with no synthetics suggests earlier.
3. Is there an RN or WPL number? Count the digits. WPL means pre-1959. Five-digit RN points toward 1960s to 1980s. Six-digit RN above 100000 means post-1990s. Look it up on rfrn.ftc.gov if you want the company name.
4. What does the country of origin say? "Made in USA" is generally a vintage indicator for the brands I work with. Obsolete country names are automatic dating clues.
5. Is there a union label? If yes, which design? Cross-reference against the ILGWU timeline above.
6. What does the brand label itself look like? Material, font, logo design, size of the label. Does it match what you know about that brand's label evolution for the era you are landing on?
7. Cross-reference. Do at least two or three of these clues agree? If they do, you have reasonable confidence. If they contradict each other, dig deeper before you buy.

What does all this actually mean for buying decisions?

Reading labels is not just an academic exercise. It directly affects what a piece is worth, whether a seller's claim is accurate, and whether you are paying a fair price.

A seller describing something as "rare 1980s Ralph Lauren" when the label shows a six-digit RN, a tagless neck print and symbols-only care instructions is either mistaken or not being straight with you. None of those features exist in the 1980s. That knowledge protects your money.

Equally, knowing how to date a label helps you spot underpriced pieces. A genuinely "Made in USA" Tommy Hilfiger heavy knit from the early 1990s, priced at €25 in a charity shop because the seller did not recognise it, is worth at least €60 to €80 to the right buyer. That gap only exists if you can read the label.

And there is the authentication angle. Fake vintage is a real thing, particularly at the higher end of the market. Reproduced labels on fake Ralph Lauren or Tommy Hilfiger pieces do exist. The physical label itself is your first defence: check the stitching, the feel of the fabric, the consistency of the font, the accuracy of the logo proportions. A label that looks slightly wrong usually is slightly wrong.

If you found this useful and want to go further, my guide on how to read vintage clothing labels and date them goes even deeper on the decade-by-decade detail, including European label conventions and a full brand-by-brand breakdown.

At Revaleur, every piece in the shop has been through exactly this process before it is listed. I check the labels, verify the dating, research the brand-specific details and only sell pieces I am confident about.
