A picture hat is an elaborate woman's hat with a wide brim, worn with gown or in formal clothes settings. They resemble sun hat and are often heavily decorated with hat flower, hat feather or other hat ornament. This style of hat was featured in virtually every decade of the 20th century and has a history dating back to at least the 18th century, as shown in pictures by 18th-century English painters such as Reynolds and Gainsborough.
