Halo hat

[4] Popular from the 1930s on, the halo hat was created in a variety of fabrics – knitted or crocheted versions could be made at home – and could be a circle or semi-circle in shape.

[5] Similarly, describing the outfits worn by racegoers at a Sandown Park meet in 1937, The Times referred to an: "aureole-brimmed" hat design.

[10] The following year, the Duchess of York was described as wearing a velvet halo hat to attend a charity matinee with Princess Elizabeth.

[11] Three years later, Wallis Simpson would wear an iconic gown and halo bridal headpiece, made by Caroline Reboux's studio in Paris and trimmed with pink and blue feathers.

While it could create a large frame around the face – as with the circular straw design that featured on the Picture Post in 1940 – it could also have more modest proportions.

[2] In the mid 1960s, British Pathé's 1964 film Hats on for Winter featured a large-scale halo design with sunburst pattern, alongside visors and caps.
