Please Note: This is just a start to this page/glossary. It is very much a work in progress. I just want to make it available promptly. At initial publication, the examples only include Godey’s Lady’s Book. Additional examples and links will be added sporadically.
This glossary will be continually developing and fluid, with links to both primary resources and additional secondary information. I will be adding and editing entries continuously. Be sure to hover over the text to find all the links.
Notice the color coding. Words used in publications between 1850 and 1865 in the context of millinery will be in blue. Words not used or very minimally used between 1850 and 1865 in the context of millinery will be in green. Words or terms used more frequently in British or European publications will be in orange.

Found an American publication with the use of Pork Pie: “is a style of hat worn by Her Royal Highness the Princess of Wales at Sandringham. It is of black velvet, and in form is oval with a broad brim turned up all round, something like the “pork pie” hat”
