I was at Acen a few weeks ago and, of course, it was great.
I must have taken some 120 pictures of just cosplayers all that weekend.
There were many FF cosplayers there, as well as the hundereds of other anime cosplayers there. But by far, one of my favorite costumes was an amazingly well done FFX-2 Rikku costume. As simple as this costume is, as far as the amount of material goes, it was very well detailed.
All I have to say is that it's a great costume. Well done, who ever you are.
