Lampshade hat

A lampshade hat is a millinery design in which the hat has a small circular crown – typically flat, but sometimes rounded – and flares outwards to create a cone-like profile. In shape, it may have some similarities to the pillbox and bucket hat, both of which were popular at around the same time, although the classic lampshade design is longer and more flared than a pillbox (typically ending at or below the ears) and is generally made of stiffer material than a bucket hat.
