Sylveon Gijinka

ColossalCon was at a time when Pokemon X/Y stuff were first being released and talked about, including the new Eeveelution and what type it could possibly be. I saw her once before earlier in the day, but couldn't get a picture. Then I waited for her after the large Cosplay Runway event that night, and "caught" her and a couple of others as they came out of the "Waiting room" after their performances.

Sylveon is

Edit: I also figured out that she created that Sylveon plushie herself. I give mad props to that.
