What do witches look like?

The way witches look like to me is evil looking. Like the witch from snow white. There could also be younger witches that wear all black and have nappy puffy hair. The witches have dry skin and skinny fingers. All witches must have a witch hat that is worn out and old. They also have their broom to fly with. The witches descrived in shakespear was that they couldnt even tell if they were male or female because they had beards. I'm guessing some witches can be so ugly that their gender cant show.
