Witch hat
A witch hat (), in popular culture, is the style of hat characterized by a conical crown and a wide brim (like akubras and gats).
The origins of the witch hat as displayed today is disputed. A common theory is that it is an exaggeration of the edgeless hats associated with the Welsh and later the Puritans, or an exaggeration of the conical hats believed to stimulate the brain of the wearer. These "thinking caps" are the precursors to the modern dunce cap. Church despised pointy hats given that the points were often related to those of the devil's horns. The witch hat is a more brimmed version of the cone-shaped hats commonly worn by male-gendered wizards and magicians, as the hat was more brimmed for it to be female-appropriate. As of the Victorian era, fairy tales began depicting black-colored conical hats and crones as symbols of wickedness in their illustrations. Another possibility is that in Luna, a town of the Etruscan civilization, there were coins on one side depicting a goddess commonly associated with witches, named Diana, wearing a brimless, cone-shaped hat.
Mildred Hubble
In "The Worst Witch" Mildred is in the Winter Term of her first year. She is shown to be tall and thin with long, black hair which she wears in pigtails. On the day of the cat ceremony, Mildred is given a tabby cat instead of a normal black cat which fails to sit on her broomstick without even trying to hold on. This prompts the form sneak and goody-two-shoes teacher's pet Ethel Hallow to taunt her about it. After losing her temper, Mildred turns Ethel into a pig (though she did it under threats of a frog transformation) whereupon Miss Hardbroom materializes in the courtyard and tells Mildred to take Ethel to the school library and reverse the spell. From then on, Mildred and Ethel become deadly enemies. In revenge for the pig transformation, Ethel curses a broom she was lending to Mildred for the Halloween celebrations at an abandoned castle. This results in the broom turning bucking bronco-like and nearly throwing Mildred off. After furiously being set an interview with Miss Cackle and Miss Hardbroom, Mildred runs away where she comes across another witch that "looks" like Miss Cackle but is actually Miss Cackle's evil identical twin sister Agatha Cackle who is jealously trying to throw a mutiny against her sister and take over the academy. In the nick of time, Mildred turns Agatha and her malevolent coven into snails and takes them back to the school, whereupon her interview is cancelled and she is made a heroine.
