[general witches] Why do many witches wear the worst possible hats for flying on a broom?

The traditional wide-brimmed pointy witch hat has many disadvantages for a flying witch:

* not aerodynamic
* no strap + wide stiff brim = would definitely catch the wind and fly off
* no eye/face protection
* no impact protection
* not warm

Why don't they wear something more sensible?

Well, to answer this question we need to ask why witches wear the pointy hat in the first place.  And to be honest, there's no definitive answer aside from "tradition", "it looks cool", and "witches like it".  Sure, some witches may keep things in their hat, such as potions, herbs, or reagents, but most witches prefer to carry such things in sacks or pouches.  Some witches believe that the pointy hat can serve as a focus for their magical power, akin to a magic wand for a wizard, but given that most witches do not cast spells with their hats, this claim appears to be flimsy at best.  

Ultimately we may need to conclude that practicality is a secondary concern for witches and their pointy hats.  It seems that, for most witches, their hat represents a way for them to proudly identify themselves as a witch.  So even if this is not the ideal headwear for broomstick flights, witches will choose to wear it anyway, and will keep it on mid-flight through magic, adhesives, or an unobtrusive chin strap.
