How to date a vintage zipper
Talon, Conmar, Crown, Lightning, YKK — the zipper is one of the fastest dating clues on any twentieth-century garment. Here is the full breakdown by brand, type, and decade, with the cases dealers get wrong.
Zippers were invented in 1893 (Whitcomb Judson's 'clasp locker') but did not work properly for fashion use until Gideon Sundback's redesign in 1913, and did not appear in women's clothing until the late 1930s. Anything with a zipper was made after roughly 1935. The brand, the tooth type, the pull tab shape, and the placement on the garment narrow that further.
The two-second test
Open a vintage garment. No zipper anywhere — closures are hooks-and-eyes, snaps, buttons, lacing. That puts the piece earlier than about 1935. A side-seam zipper at the left hip and metal teeth: 1935–1960. A back-seam zipper, nylon coil: 1960s onward. Invisible zipper: post-1968 at the absolute earliest, more realistically 1970s. Plastic moulded teeth: late 1960s onward, peaking 1970s–80s. That is most of the dating value in fifteen seconds.
Brands and their dates
Brand stamps appear on the back of the slider or on the pull tab. Use a loupe; some are tiny.
| Brand | Active dates | Notes |
|---|---|---|
| Talon | 1913–1990s (now revived) | The Hookless Fastener Co. of Meadville, Pennsylvania — first commercially successful zipper. Talon dominated American garments through the 1950s. Late Talon zippers in the 1980s exist. |
| Crown | 1930s–1970s | Crown Fastener Co. (USA). Common on American 1940s–60s women's wear. Stamped 'CROWN' on the back of the slider. |
| Conmar | 1933–1960s | Conmar Products Corp. (USA). Often used by mid-tier American manufacturers in the 1940s–50s. |
| Lightning | 1933–1950s | British zipper brand. Found on UK-made garments and pre-war Paris couture. 'LIGHTNING' stamp on the pull or slider back. |
| Eclair | 1926–present | Eclair Prestil (France). Standard zipper on French couture (Dior, Balenciaga, Schiaparelli) through the 1960s. |
| YKK | 1934–present | Yoshida Kogyo Kabushikikaisha (Japan). Almost invisible in Western fashion before 1960. Dominant from the 1970s onward. 'YKK' stamp on the slider back. |
| Coats / Coats Opti | 1980s–present | Coats Opti (UK) replaced Lightning. Common on later European garments. |
Tooth construction
Three main types: metal (brass or nickel), nylon coil (a continuous spiralled monofilament), and moulded plastic (individual plastic teeth bonded to the tape). Each appeared at a specific point in time and each has a characteristic feel.
- Metal teeth, brass: 1913 onward. Common until about 1960.
- Metal teeth, aluminium or nickel: 1930s–1960s. Often used to save weight in lightweight dresses.
- Nylon coil: 1940s in industrial use, mass-market fashion from about 1960 onward. The teeth are a continuous spiralled monofilament, not separate elements.
- Moulded plastic: late 1960s onward. Individual plastic teeth bonded to the tape. Often coloured to match the garment. Peak use 1970s.
- Invisible zipper: patented 1959, mass production from the late 1960s, widespread in fashion only from the 1970s. The teeth are hidden behind the tape on the reverse.
Placement and what it tells you
Where the zipper sits on the garment changes by decade and is a reliable secondary clue.
| Placement | Era |
|---|---|
| Side seam at left hip | 1935–1960. Standard for dresses through the 1950s. |
| Centre back, hip to neck | 1950s–1970s. Becomes standard with the New Look and after. |
| Centre front | Sportswear and 1970s onward; uncommon in formal dresses pre-1970. |
| Invisible, back centre | 1970s onward. Couture-leaning. Very rare before 1968. |
Pull tab shapes
Subtle but useful. Early Talon pulls (1930s) are rounded leaf shapes. 1940s Talons standardise into a flat oval or 'dog tag' shape. 1950s pulls are often unmarked rectangles. The 1960s see decorative chrome teardrops. 1970s YKK pulls are flat triangles. Modern pulls are often branded with full logos. Mismatches between pull and slider (a 1940s slider with a 1980s pull) usually indicate a replacement.
The 1968 invisible-zipper rule and its exceptions
Most dating guides state flatly that invisible zippers post-date 1968. The invisible zipper was patented by YKK in 1959 and produced commercially from then. Couture use began in the early 1960s but was very rare. Mass-market use is post-1968. So if you see an invisible zipper, the safe interpretation is 1970s or later. If the rest of the garment looks 1950s, you may be looking at a 1980s or 1990s reproduction.
I have seen exactly one Halston piece with what reads as an invisible zipper from 1972 — most others from the same period pull over the head, no closure at all. Halston was a fastener-minimalist by preference, not by necessity.
Frequently asked
Can a zipper be replaced without destroying the value of a vintage garment?
Yes, if done carefully. A like-for-like replacement (same era, same brand if possible) by a textile conservator does not significantly reduce value on most pieces. A modern YKK zipper in a 1950s dress materially reduces value and should be disclosed. For couture pieces (Dior, Balenciaga, Chanel) any closure replacement should be done by a specialist and documented.
What if there's no zipper brand stamp visible?
Stamps on early metal zippers wear off over time. Use the tooth construction, the slider shape, and the placement to estimate the era. Unstamped metal zippers are most common 1930s–1950s; unstamped nylon coil is most common 1960s onward.
Is a metal zipper always older than a plastic one?
Not necessarily. Couture houses continued using metal zippers (Eclair brass) well into the 1970s for quality reasons. Cheap 1970s mass-market garments used nylon coil. The combination of zipper type plus garment construction usually clarifies; a metal zipper on serged interior seams is later than a metal zipper with hand-bound seams.
