Du Barry Patterns were manufactured by Simplicity Pattern Company.

Begun in 1931 for selling exclusively at Woolworth Company Stores.  The latest date found is 1947.  Original prices ranged from 10 cents to 15 cents. 

Notice on the earliest pattern that it is  du Barry and was later changed to Du Barry.

Between 1933 and 1936 Du Barry patterns were marked with the NRA logo to support the National Recovery Act.

Because of their short production time they are harder to find and are considered highly collectible.

Du Barry patterns are hard to date by number.  They seem to skip around and some have a B behind the number and some have a D in front of the number and there are even some with a T. 

After several years selling and handling old sewing patterns and catalogs, I have compiled this list of dates and pattern numbers.  Since most patterns are not printed with the copyright information on them this list is computed using information from magazines, pattern books and other published sources.  The best I can do most of the time is assume that if a pattern is published in a catalog that is it's date of release.  There are of course crossovers and some patterns are rereleased.  So there is definitely room for error in my calculations. 

This guide is meant as just that.......A GUIDE.  It is not a definitive copyright date source.

Many Thanks to: Erin at "A Dress A Day" for creating the wonderful "Sewing Pattern Wiki", all of the contributors to the Wiki, and all of my wonderful friends and pattern sellers, (especially Birgit at Stitches and Loops ) and collectors who share their information and photos and knowledge.  (there are too many to list here, but you can find them on my Links Page,) and last but definitely not least, my Dear Husband for giving me tons of help and encouragement to research all of the data to compile for your research benefit.
