What I have so far for my costume:

Cat ears (Headband) and cat tail: were from last year, I got them from Party City
Hot I got the bow on there: Bow is from my large Hello Kitty plushie that fell off it and I tied the bow on the tail with a black string
Platform shoes: IDK where I got them
t-shirt: IDK where it's from
All I need are a white skirt and a pink wig
