In the early Edwardian period, hats were a fashion accessory, rather than a necessity. Most were kept fairly small, sitting on the top of the head atop a pile of hair. More masculine styles had begun to emerge during the 1890s, and some of these were still popular during this period.
Women were seen wearing traditionally male styles such as the “Boater” or “Trilbys”. Bonnets had grown out of style, and women preferred hats that soared above the head, sometimes called “3 Story” or “Flower Pots”.
