Other related items that can be collected along with vintage patterns are old pattern books from fabric stores and departments and monthly or quarterly pattern magazines that were issued by the pattern companies.
These publications are invaluable tools for designers, students of apparel design, the custom clothier who specializes in vintage fashion, and the vintage fashion enthusiast.
In mid 1967 the standard changed once again and a Size 12 became a 34 inch bust and remains so today.
So if you are trying to date something near the year of size change, the size can be a great clue.
(With unprinted patterns you match notches and cutouts together).You must consider the general silhouette of the clothing along with other factors such as hair, price, sizing and envelope style and logo placement you can get pretty close to the issue or copyright date.Please be aware that even if a pattern is dated, it could have been in production for years and could even be a re-release of a previous number. For instance it is very difficult to tell a 1938 pattern from a 1941 pattern. The same thing applies for 1959-1961 and again in the 60s and 70's.The artwork on the envelopes can also be a thing of beauty to behold all by itself.For those who cannot find the vintage styling they want in their size, fabric, or price range, vintage patterns afford the ability to have exactly what one wants, the way one wants it, whether one sews it up at home or retains the services of a custom clothier.
