What is the British Easter tradition of wearing a flower-decorated hat called?

An Easter bonnet is the British Easter tradition of wearing a flower-decorated hat.

Easter bonnets are ornamental hats associated with springtime and Easter celebrations. They may be decorated with flowers, ribbons, bows, eggs, chicks, rabbits, or other seasonal designs. Children often make them for school events, church gatherings, and local parades, while adults may wear more formal spring hats.

The tradition developed from the wider practice of wearing new clothes for Easter. In Christian communities, new clothing could symbolize renewal and the new life associated with the Resurrection. The hat became a particularly visible and playful part of Easter dress.

An Easter bonnet is not necessarily a specific historical hat shape. The term usually describes the decoration and occasion, so designs range from simple floral hats to elaborate craft creations.
