In terms of Kuroshitsuji II Alois Trancy, he is head of Trancy Household and a cute teenager (appearance) with pale blonde hair and blue eyes. And there always are so many male and female cosplayers (most of them are girls) obsessed with this Black Butler cosplay that we could see Alois here and there.
And the purple anime costume that comes with long, purple frock coat, green vest with black stripes and back, white shirt, black tie and black short, is the popular one, along with the brown boots with purple bow. Additionally, there are many other cosplay outfits of him, such as the girl version maid clothes and the pink and white Ciel in Wonderland outfit and so on. In one word, this is a must-try for most cosplay girls.
