A half hat (also sometimes half-hat) is a millinery design in which the hat covers part of the head.[1] Generally, the design is close-fitting, in the manner of the cloche, and frames the head, usually stopping just above the ears. It may be similar to a halo hat in the way that it frames the face and can be worn straight or at an angle.[2] The half-hat is said to have been created by the French-born and US-based milliner Lilly Daché, who won an award for the design in 1941.[3]
