As a general rule though the majority of zips found in clothing between the Thirties and mid to late Fifties were metal, but this is not a hard and fast rule.
Some companies were still widely using metal zips well into the Seventies. It is rare to see a Fifties dress with an original nylon zip, but from time to time you do find them, particularly on lighter weight dresses where a metal zip would have probably looked incongruous.
Therefore, whilst it is common to see advertisements for nylon zips from the mid Fifties onwards, it is not often you find dresses with them.
I tend to find that there were a few specific companies that were producing their garments with nylon zips relatively early on. I have had five or six dresses by the brand, all with nylon zips and all dating from the late Fifties.
When I visited the exhibition of her work at the Met museum last year I was surprised to notice quite how heavy duty the zips on her light and feminine evening dresses were.
Searching for vintage clothing is just as fun as wearing the retro finds.
However, a lot of clothing these days is influenced by vintage styles.
Thrift outlets are chaos but I do seem to find one-of-a-kind vintage garments that are usually grabbed off the rack within seconds at the busiest Goodwill. Thrift outlets offer a variety of items but lack any kind of order. You must go where no other vintage lover has gone before, Goodwill Outlet.
Check out this source for a Goodwill Outlet World near you. As modern styles seek inspiration from clothes of the past, a new vintage hunter might be tricked simply from the garment’s style.
