I made this Zatanna almost specifically for my appearance on the 'Attack of the Show' program to show 'a work in progress'.  
The base is a JLU Black Canary chosen of course for the jacket she wears which was turned into a tux tail coat with help from a STAS cape and sculpted lapels, bowtie and vest. Her hair was practically rebuilt with Milliput. Her shirt cuffs and buttons are sculpted. The hat is from a BTAS Mad Hatter that has been heavily modified and the cane is just from the ol' parts bin.
