so I'm doing a Sakizo Food Cosplay for Fanime 2013~ [link]

I was talking to my friend and shes like my long lost twin~ i showed her the Mint Chocolate version of the one im doing and she was in Love~ so we have the outfit down but we cant decide on how we want to do with it for the hair.
Since the outfit shes doing isnt drawn on a person we came up with two ideas but cant decide.

Idea 1: Twin it up and get the same wig.
Idea 2: Do opposite colored wigs~ Have her (mint chocolate) with a  dark brown wig since her outfit is really bright.
so it opposite b/c Chocolate has Blonde hair with a dark colored outfits~

We cant decide on what to do~ help~! opinion?
