I love Alice in Wonderland~ It was my first group cosplay last year. I honestly think since you want an edgier Alice to go with a layered/multi colored wig, plus the outfit itself has a ton of different patterns I say since it is wonderland not to stop at the hair! Here are some color combos I think will work. I also like the idea of a short haired Alice since it would look nice with the headdress and allow the outfit it be shown off more.
(black and red)
(blond like this I can see)
(Black and Burgundy)
My fav. selections are the first and the last but that's just me X3

Their greatest error was thinking that they could make us into willing puppets who would fill the thankless
role of your everyday villain without complaint... They were wrong!
