This millinery velvet black hat is vintage, likely 1940's era. Beautiful and in excellent condition! The hat measures 13" across on the outside. The opening measures 7". I'm not sure about what "size" it is, so I listed 7 as in 7" or medium. The main part of the hat is velvet with satin around the brim and a satin ribbon. The ribbon and brim are a light black (not grey as the picture looks).
