Vintage Reference Page
This is a list of website and reference books that I have used when researching age and care of vintage and antique garments and accessories. I'll be adding to this page so it is a work in progress. My mother, Kitty Greene is my go to personal reference. After spending fifty years sewing, and working as a garment quality control auditor in the clothing factory in the 1960's, she is a wealth of information on sewing construction and history.
My favorite reference book on antique textiles and fabrics: Vintage Fabrics Identification and Value Guide copyright 2006 Joan Reed Kiplinger, Judith Scoggin Ridley
When researching union made in USA garments, Cornell University website was a wealth of information. http://ilgwu.ilr.cornell.edu/timeline/union-label-timeline.html
Sharon's Vintage Jewelry is an excellent website and she has an excellent library reference guide regarding vintage and antique jewelry . http://www.sharonsvintagejewelry.com/pages/my-library
Vintage Fashion Guild http://vintagefashionguild.org/ for designer fashion labels.
For sewing, garment construction, Singer Sewing Book, The Complete Guide to Sewing Revised Edition, Jessie Hutton, Gladys Cunningham, Golden Press New York, 1972. I prefer the older edition because it documents older fashions and construction that were trending at the time.
