Look For Date Tags On Clothes

If you want to know how to date vintage clothing, the easiest and most intuitive step to is to look for a date tag on clothing, AKA the copyright year.

Woohoo, hard work done! Not so fast. Date tags provide an easy way to date and verify your vintage duds, but unfortunately, they’re not listed on all garments. In fact, they’re rather few and far between, but you still always start by checking just in case.

Keep an open mind though, because the year might not be in a standard format, but rather something like SP78, indicating the garment was part of a brand’s 1978 spring collection. That copyright year can also refer to the brand itself, not the style/design of the garment.

Still, it’ll help you narrow your dating detective work down to at least an era.

Look For The "Made In" On Vintage Labels

“Made In USA” Vintage Tags

The words “Made in USA” or a vintage tag featuring the American flag is another, well…flag to help you know spot vintage clothing.

The average 1960s American home spent a significant amount on their wardrobe, investing the equivalent of roughly $4,000 in today’s money for fewer than 25 garments each year. About 95% of them were produced domestically.

All of this started to change when Asia and Latin America opened large factories and textile mills around the mid-1970s. Domestic textile production took a nosedive and was practically non-existent by 1990.

Labeling garments with “Made in the USA” became a badge of honor and while several fashion brands have started to resurrect American-made garments, “Made-in-the-USA” tags are still generally associated with clothing produced around the 1980s.

Much like the USA, “Made in Australia” clothing tags also typically suggest the item is likely to be vintage for similar reasons.

“Made In Mexico” Vintage Tags

Mexican travel = Mexican textiles. Seeing “Made in Mexico” (or “Hecho en México”) verbiage is indicative of a surge in travel to Mexico that took place around the 1950s.

The war was over, air travel was booming, and the Pan-American Highway’s Mexican section was completed. Mexico provided an affordable, reachable travel destination for both A-list celebs and everyday folks, so American women embraced Mexican styles, bringing back circle skirts and souvenirs.

Use Union Tags

Vintage Clothing Labels – How to Identify and Date Them #vintageclothinglabels #vintageclothingtags #vintageclotheslabels #vintageclothestags #howtoidentifyvintageclothing #howtoknowifclothingisvintage #howtoreadvintageclothinglabels howtoreadvintageclothingtags #sustainablejungle Image by Sustainable Jungle

Unions like the International Ladies’ Garment Workers Union (ILGWU) began to emerge after the turn of the 20th century. If you see a union label from ILGWU, you might have something from as early as 1920 and as late as the 1980s.

While that verifies vintage status, that’s still a pretty broad date range. Narrow it down further via other specific details, like the National Coat and Suit Industry Recovery Board logo used from 1938-1964. The words “Amalgamated Workers of America” or simply “Union Made” were used between 1934-1976.

Take Note Of Sizes

Vintage Clothing Labels – How to Identify and Date Them #vintageclothinglabels #vintageclothingtags #vintageclotheslabels #vintageclothestags #howtoidentifyvintageclothing #howtoknowifclothingisvintage #howtoreadvintageclothinglabels howtoreadvintageclothingtags #sustainablejungle Image by Sustainable Jungle

Shorter women and curvy women with hourglass figures reportedly brought about the need for half sizes, which emerged around 1940. Seeing “½” after the size denotes a garment’s shorter length and date of production between the 1940s and 1970s.

You can also use this info to help size your vintage garments: Half sizes were typically 1/2″ to 1/4″ smaller than modern sizes, so a vintage tag with 9½ would actually be closer to a modern 8 or 8½. However, half sizing was never a standardized industry practice. Different brands, like Sears, employed their own half sizing systems, so that’s only a loose rule of thumb—kind of like the modern women’s clothing size system!

You can also look for odd numbered sizes, like those used today’s juniors department. But “Junior” clothing didn’t really make an appearance until the early 1980s. Prior to that, odd sizes were actually used for adult clothing. Seeing a vintage tag that’s size 3, 5, 7, 9, etc. could suggest it was produced before the 1980s.

Look For Lot Numbers

As more and more garments were produced in factories in the 1970s, lot numbers were utilized to keep track of them. When foreign production began to take over around 1979, the numbers ceased to exist.

Vintage tags with this will say “Lot” followed by a letter or number, providing a fairly safe bet that piece was produced sometime in the 1970s.

Reference The Address

Imagine buying a sweater and seeing an address on it. Talk about knowing #WhoMadeMyClothes!

Back in the day, it was somewhat common for the designer to include their address. Pair that with another historical fact—that zip codes didn’t exist until 1963—and you’ve got another trick for how to know if clothing is vintage. If you see an American address sans zip code, you’ve scored something made before 1963.

And anything with an address at all was likely at least still made in the 20th century.

Check For Woolmark Logos

Ironically, consumers knew the value of natural fibers over synthetic fabrics long before they regained popularity in recent years. With an aim to help shoppers choose wool clothing, a Woolmark logo was developed in 1964 as a marketing technique to encourage consumers to shift away from increasingly popular acrylic and polyester.

Here’s a quick guide on using this symbol in dating and identifying vintage clothing tags:

  • Wool garments without a label identifying them as wool = made pre-1939
  • First Woolmark logo (indicating 100% wool) = made after 1964
  • Woolmark Blend logo (indicating 60% wool) = made before 1971
  • Wool Blend logo (indicating 50% wool) = made before 1999

Take Note Of Material Brand Names

Before synthetics became so popularized and widespread, their use was a lot more niche, particularly by specific brands that initially created that fabric. Looking for these specific branded names of generic synthetic materials can help you date vintage clothes.

The most commonly known one is Lycra because this name is still used. Invented in 1959, it’s the brand name of spandex/elastane.

Other synthetics once had brand names, too. Nylon was first produced in 1939 and the brand Qiana produced it between 1968 to the mid-1970s. Acrylic, under the brand names Acrilan, Creslan, Orlon, and Zeran, was sold after 1950. Polyester’s commercial use began in 1953 and brand names Celanese, Dacron, Kodel, and Vycron were big in the 1970s (think: disco-ready bellbottoms).

Look For Countries That No Longer Exist

It’s not uncommon to see countries from yesteryear on vintage pieces—which requires you to do a bit of historical sleuthing. If something was made in Newfoundland, for example, you can date that garment between 19071949, or until the self-governing Dominion became a Canadian province.

“Made in Yugoslavia” tells you a garment was made between 1929 and 1992.

Similarly, colonial rule can also help to date vintage garments. Seeing “French Indochina,” “Indochinese Union,” or “Indochinese Federation” could give you hints about a garment being made prior to 1947 or up until 1954 (in the case of the latter).

Use The RN Number

Vintage Clothing Labels – How to Identify and Date Them #vintageclothinglabels #vintageclothingtags #vintageclotheslabels #vintageclothestags #howtoidentifyvintageclothing #howtoknowifclothingisvintage #howtoreadvintageclothinglabels howtoreadvintageclothingtags #sustainablejungle Image by Sustainable Jungle

Registered Identification Numbers (RN) are required in the US for businesses involved in the production, distribution, or finishing of a garment. The RN number system first came about in 1952 and, up until 1959, used RN numbers 00101 to 04086. In 1959, the numbering system underwent a makeover and started at 13670.

RN numbers won’t indicate when the actual garment was produced but they hint about when the company was first granted the number—which can still be helpful with knowing how to read vintage clothing brand labels.

It’s generally thought that RN numbers with just 5 digits are on clothes produced in the 1960s and 1970s. Garments produced in the 80s or later might have 6 or more digits.

Take A Hint From Care Labels

Garment care guidelines are a key component of learning how to read clothing labels from any decade. For vintage clothing, they provide more info than just how to keep that gogo dress gogoing for years to come.

In 1971, the US Federal Trade Commission mandated that manufacturers and importers of clothes include garment care instructions on clothing labels. The “Care Labeling Rule” (which was recently almost rescinded) meant that vintage tags after 1971 listed at least one method of care (i.e. “dry clean only;” “machine wash cold”).

If no care instructions are listed, it’s likely a vintage garment made prior to 1971.

Care symbols on clothing labels, along with written instructions, appeared in the US in 1996 and after 1998, the symbols could be used without written instructions.

Why Care About Vintage Clothing Labels?

Firstly, it’s just fun to find and identify truly vintage items. Knowing that your find is unique and has potentially been around longer than you have is super satisfying!

Secondly, advocating for vintage helps us value what we already have and avoid fast fashion, and when our pre-loved garments come from previous generations, the labels are like a peek into history.

But maybe that’s just us? If you’ve got this far, tell us why you’re looing to better understand your vintage tags?
