I started with this black and red wig and trimmed the front a bit. At first, I styled all of it up in the back, but then I took it down.
On top, I added a leather headpiece by Faerywhere on Etsy and some cheap black foam horns for height.
I found a shiny red apple shaped purse on AliExpress and swapped in a black corded handle that visually disappeared, so I could offer a poisoned apple to sweet young things (and also hold my cellphone!).
