Sorry that I didn't reply to this before ... But, isn't that the same wig that was originally on many of the circus clowns (only in a different colour) ?
I guess, we are even with this now. 

Yes, you are completely right. It is the clowns wig. 
The scarecrow has the same haircut as well.  

There is a very nice new wig for royality in any 
knights theme in the new cinderella set, btw.  

I would love to have that wig's number.
best,
