MCM london expo?

So a friend of mine and her friend are going to MCM expo in london in october, tickets are gonna go on sale soon but i don't know if i should go or who i should go as.

my friend had an idea for me to make a harley quinn cosplay, involving me dying a pair of white leggings red and a white top red on one side and black on the other and then like painting diamonds shaped on and then getting a hat and then painting my face for it
Buuut i would like to go as like hungary (aph) or souseiseki (rozen maiden) though if i ever get around to dying my GOD DAMN HAIR (dye is downstairs, sister and mum being gay about it) and if i like it, i might keep it so does anybody know of a character with red-purple hair?

~garu over and out
