The zipper is the most reliable single dating clue in vintage clothing. Its introduction, evolution, and the shift between materials can narrow manufacture date to within a few years.
Pre-Zipper Era (Before 1935)
Women's fashion before the mid-1930s used hooks and eyes, snaps, and buttons. The zipper was invented in 1913 (Whitcomb Judson's "clasp locker") and refined into the modern zipper form by Gideon Sundback in 1917, but its adoption in women's fashion was slow.
Any garment with no zipper and hooks-and-eyes or snap closures almost certainly predates 1935. This is not absolute — some designers continued using hooks through the late 1930s by preference — but it's a reliable first check.
The First Zippers in Fashion (1935–1945)
Elsa Schiaparelli popularized the zipper as a fashion element in 1935. The earliest fashion zippers had brass or nickel metal teeth on a cotton tape, with a metal pull. Early metal zippers are heavier and more substantial than later versions.
Placement: side seam placement was most common for the first decade of zipper use. Back zippers were less common until the late 1940s.
Brand markings: the earliest fashion zippers often have brand names embossed on the pull — Talon was the dominant American manufacturer. A Talon zipper with a particular early logo design can be dated within a small range.
Post-War Metal Zippers (1945–1963)
Metal teeth zippers dominated through the late 1950s and into the early 1960s. Several identifying features:
Brass teeth: most common in quality garments; heavier, warmer gold color than nickel. Nickel/aluminum teeth: lighter color; used in cheaper garments and as aluminum became more available. The pull: metal pulls were often decorative and brand-marked. Talon and Crown were the dominant brands.
Side vs back placement: from the late 1940s, back zipper placement became increasingly common. Side zippers persist into the 1950s especially in skirts.
The Nylon Coil Zipper (1963 Onward)
The nylon coil zipper — a continuous spiral of nylon rather than individual metal teeth — was introduced for mass use in the early 1960s. By 1963–1964 it was widespread in American mass-market clothing.
The transition was not instant: quality garments continued using metal zippers into the late 1960s, and some through the 1970s. But nylon coil zippers in fashion are almost exclusively post-1963.
Plastic Molded Tooth Zippers (1970s Onward)
Plastic tooth zippers — individual molded plastic teeth on a synthetic tape — became common from the late 1960s. The large, chunky plastic zipper became a design element in 1970s fashion, particularly in polyester garments.
Large decorative plastic zippers with colored or oversized pulls are a strong 1970s indicator.
Invisible Zippers (1960s Onward)
The invisible zipper (where teeth hide behind the tape when closed) was introduced in the early 1960s. Invisible zippers in fashion indicate mid-1960s or later.
The Quick Dating Formula
No zipper + hooks and eyes = pre-1935 most likely Heavy metal brass zipper, side placement = 1935–1960 Metal zipper, back placement = 1945–1965 Nylon coil, fine gauge = 1963 onward Large plastic decorative zipper = 1970s onward Invisible zipper = 1965 onward
What Zippers Can't Tell You
Zippers can establish a floor date (the garment cannot predate the zipper type) but not a ceiling. A garment with a nylon coil zipper could be from 1963 or 2023. Always combine zipper evidence with fabric, construction, and label evidence.
Replaced zippers — where an original zipper was replaced with a later type — are common in well-worn pieces. If a zipper looks newer than the rest of the garment or is a mismatched color, it may have been replaced. Check the tape color and stitching style around the zipper for signs of replacement.
