Little Sister from Bioshock Modeled/created by me. Altered patterns for the dress, dyed several times, thoroughly distressed/weathered. Syringe made from vintage gas pump nozzle, a PVC pipe, a wooden dowel, etc.
I've seen a lot of little sisters and a number of them go overboard on the make up and it ruins the look, but your version, there's damage and distress but it's all balanced out with very small touches that look like you spent a lot of time slowly cultivating the details to give it a good feel of random. Did you whiten the top of your face? I seriously think I just found my favorite Little Sister cosplay.
