A doll wearing the big hat!
Nothing happens!
That's only to be expected of course: for its witch, the big hat is just a fashion statement in the end. Nothing but a fun stereotype to adhere to!
But the doll feels powerful!
Not magically powerful, admittedly, but -
It likes the shadow its cutting.
Its silhouette.
How it looks in the mirror.
A witch that was watching her doll admiring its reflection!
A witch that lets her doll keep her old big hat and makes herself a new one!
A witch and doll both wearing big hats!
Breathtaking!
