What is a demi-millinery?
Demi-millinery is a place where Miss Moss crafts her ornaments.
Demi is french for partial or half,
Millinery is the art and trade of designing and making women’s hats.
Miss Moss doesn't just make hair bows, they are more than that, they are not hats, hairpieces bring to mind toupées and falls while headpieces conjure images of something much more structural like something Cleopatra might wear.
And so the word demi-millinery was formed.
