i think i would use some concealer stuff and that creamy stuff they use for a base whose name escapes me for the scar...i'd use a combination of that...or like, i dunno,that tanning lotion>? make sure it doesn't run when you sweat...or something.
i would use henna for the tattoo,but what would i know? i think you should go find some renji cosplayers and ask them what they used for his tattoos, they're rather similar.
as for the coat, just rummage for things you can alter or just sew up one yourself, it shouldn't be that hard.
Akatsuki cloak, random lolita, maybe aria, maybe soul eater
prolly Otakon 2011, maybe NYAF.
You are a neglected Cosplayer when you look for photos of yourself forever after a con and you cannot find more than three. If you are, join the club, and begin your post with something related to neglected cosplayers!
