Attached to the edges or bands of hats, hat clips added extra style or color. In the 1930s, they would have been added to small and rather tight-fitting cloche, or bell-shaped, hats. The angular forms of this clip suggest the popular Art Deco style, which was prominent during the inter-war period. The material is Bakelite, an inexpensive plastic that could be shaped into a variety of fashionable products.
