This costume debuted at KumoriCon 2013, designed specifically to be worn while Queenie was in her Jotun!Loki cosplay (she had to be painted, and this one was quick to get on).

[UPDATE: 2015]
Still love this costume; much like Sherlock, it's easy to get on and off, and nothing about it was handmade, so it'll probably get some more use before retirement.
