Vintage clothing is generally defined as clothing that is at least 20 years old but less than 100 years old. Anything older than 100 years is considered antique. Anything newer than 20 years is secondhand or pre-owned, not vintage. "Retro" is different again. It means new clothing made to look old.
That's the short answer. The longer answer is that the 20-year line is a convention of the trade rather than a law, and there are good arguments for reading it loosely. Here's how it actually works, and how to tell how old a garment is when the label won't tell you.
What counts as vintage clothing?
The widely used standard in the vintage trade is the 20-year rule: a garment becomes vintage once it's roughly two decades old. As of 2026, that means anything made in 2006 or earlier has crossed the line: Y2K-era clothing is now, uncomfortably for some of us, vintage.
The rule is a rolling one. It moves forward every year. This is why "vintage" felt like it meant 1950s dresses a decade ago and increasingly means 1990s workwear and 2000s sportswear today.
Two caveats worth knowing:
- Sellers stretch it. Plenty of listings call a 2015 garment "vintage." That's marketing, not a category error worth arguing about. But know what you're buying.
- Purists tighten it. Some dealers won't call anything vintage unless it's pre-1980, on the grounds that construction quality and manufacturing methods changed materially after that. There's a real argument there, and it's about more than age.
Vintage vs. antique vs. retro vs. secondhand
These four words get used interchangeably and they don't mean the same thing.
| Term | What it means |
|---|---|
| Vintage | Roughly 20–100 years old. Made in the era it represents. |
| Antique | Over 100 years old. In clothing, this means pre-1926: Edwardian, Victorian, and earlier. |
| Retro | Newly manufactured, designed to imitate an older era. A 2026 shirt cut like a 1970s shirt is retro, not vintage. |
| Secondhand | Any previously owned garment, regardless of age. All vintage is secondhand; most secondhand isn't vintage. |
| Deadstock | Old but never worn or sold. Vintage-aged, new condition. Often the most expensive category. |
How old does clothing have to be to be vintage?
Twenty years, by the common standard. But because the line moves, it's more useful to think in decades than in a countdown:
- Pre-1926: antique
- 1920s–1950s: true vintage, increasingly collector territory
- 1960s–1980s: the heart of most vintage inventory
- 1990s: comfortably vintage now
- 2000s: crossing the line as of the mid-2020s
- 2010s onward: secondhand, not vintage
How to tell how old a garment actually is
Most vintage doesn't come with a date on it. These are the details that give it away, roughly in order of how reliable they are.
Union labels
If a garment carries an ILGWU (International Ladies' Garment Workers' Union) label, you can date it fairly tightly by the label's design. According to the Vintage Fashion Guild:
- 1955–1963: a design without AFL-CIO attribution
- 1963–1974: a revised style found on 1960s garments
- 1974–1995: red, white, and blue, tied to the union's "Buy American" campaign
The ILGWU merged into UNITE in 1995, so an ILGWU label means the garment predates 1996. That's one of the cleanest hard cutoffs available to you.
Care labels
Care instructions became a US labeling requirement in the early 1970s. A garment with no care tag at all, and no sign one was cut out, is often pre-1970s. Not conclusive on its own, but a strong hint when it lines up with other details.
RN numbers
An RN (Registered Identification Number) is issued by the FTC to firms handling textile products in the US. Lower numbers generally indicate earlier registration, and you can look a number up in the FTC's public database to identify the manufacturer.
One thing most guides get wrong: RN numbers are optional. The FTC does not require a business to hold one, so their absence tells you very little. Their presence is useful; their absence isn't evidence.
Stitching
On American-made T-shirts, a single line of stitching at the sleeve and bottom hems, called "single stitch," generally indicates pre-mid-1990s production. Double stitching became the norm afterward. This is a rule of thumb rather than a law, and it applies most reliably to US manufacturing.
Zippers and hardware
Metal zippers dominated until nylon coil zippers took over through the 1960s and 70s. Brand names on the zipper pull, things like Talon, Conmar, Scovill, are datable in themselves, and a metal zipper with a fabric tape end is a good early indicator.
Construction
Selvedge seams, French seams, hand-finished hems, and generous seam allowances all point older. Overlocked raw edges and minimal seam allowance point newer. Cheap construction has always existed, so read this alongside the other signals rather than on its own.
Is vintage the same as secondhand?
No. All vintage clothing is secondhand, but most secondhand clothing is not vintage.
The distinction matters more than it sounds. "Secondhand" describes ownership history. "Vintage" describes age and, implicitly, a claim about how the thing was made. A 2019 fast-fashion shirt and a 1972 workshirt are both secondhand. Only one of them was built to be repaired.
There's a third distinction that gets collapsed even more often: curated secondhand versus bulk secondhand. A thrift store accepts whatever it's given and prices by volume: the sorting is your job. A curated shop buys individual pieces on purpose, checks condition, measures them, and describes the flaws. You're paying for the hours someone spent not buying the other ninety-nine things.
Why worn clothing is worth buying
There's a Japanese idea underneath all of this that's worth knowing about. Sabi describes the beauty that arrives with age and use, patina, fading, the softening of a fabric that's been washed two hundred times. It's the other half of wabi, the beauty of imperfection and simplicity.
The most direct expression of it in clothing is boro, Japanese textiles mended over generations with visible patches, and sashiko, the running-stitch technique used to do the mending. In both, the repair isn't hidden. It's the point. A garment with fifty years of visible history isn't a damaged new garment. It's a different object.
Where to buy vintage clothing
Roughly in order of price and effort:
- Thrift stores: cheapest, highest effort, no guarantee anything good is there on any given day
- Estate sales and flea markets: better odds on genuinely old pieces, requires knowing what you're looking at
- Online marketplaces: enormous selection, wildly variable accuracy in dating and condition
- Curated vintage shops: fewer pieces, higher prices, condition and measurements already done for you
At sabi, our Second Hand collection sits in that last category. Every piece is selected individually, inspected, measured, and photographed as it actually is, flaws described rather than cropped out. We're an online boutique based in Portland, Oregon, and we buy the way we do because a mended garment is usually the reason we bought it.
Frequently asked questions
What is considered vintage clothing?
Clothing between roughly 20 and 100 years old. Under 20 years it's secondhand; over 100 years it's antique.
How old does something have to be to be vintage?
About 20 years. As of 2026, that means garments made in 2006 or earlier. The threshold moves forward each year.
Is vintage clothing the same as antique clothing?
No. Antique clothing is over 100 years old. Vintage is 20 to 100 years old.
What's the difference between vintage and retro?
Vintage garments were made in the era they represent. Retro garments are new, made to imitate an older era.
How can I tell how old a piece of clothing is?
Check the union label (an ILGWU label means pre-1996), whether a care tag is present (care labels became required in the US in the early 1970s), the RN number, single versus double stitching on hems, and zipper type and brand.
Is all secondhand clothing vintage?
No. All vintage clothing is secondhand, but most secondhand clothing is too new to be vintage.
