Halloween // Help Needed!!

A few months ago I got a split dye of black and pink, it’s my first time having a halloween with colored hair and I have no clue what I’m going to do for a costume.

I don’t want to wear a wig as I have no clue where to find decent quality ones, and I doubt I could figure out how to put one on well enough to look decent.

I don’t know any characters that have black and pink hair, and I’m kind of stumped.

Any thoughts or ideas?
