I found many wonderful cosplay costumes here. The wigs are also awesome!

In a manor house on the outskirts of Victorian era London, butler Sebastian Michaelis serves Ciel Phantomhive, the twelve-year-old head of an English noble family as well as a toy and candy empire. Sebastian carries out any task required by his master and solves the problems plaguing England with ease and perfections because of his demonic lineage and Faustian contract with his master.
Grimmjow Jeagerjaques is the Sexta Espada, signified by the "6" tattooed to his back. His name stems from that of an architect named Nicholas Grimshaw. Grimmjow is very disrespectful, never using honorifics and having little respect for authority figures. He is often openly insulting to such people save for SÅsuke Aizen, and even this respect is quickly abandoned when Aizen is out of earshot. Grimmjow has an overly violent lust for battle, always seeking out the strongest opponent in a given area and he is very confident in his abilities, believing himself to be equal to, or even stronger than the fourth Espada, Ulquiorra Cifer.
