Let me start by saying this:
I've been waiting to do this costume for a billion years. Well, not a billion. Actually, it could be a billion, what with being a time traveler and all...
Anyway. More accurately, three or four years.
Whenever I got around to making cosplay or whatever.
I was replaying Chrono Trigger, and I forgot how terribly awesome Lucca is, and how much I loved her.
Finally, Sora-tan started playing the game and expressed an interest in cosplaying Crono. I leapt at the chance, and a month or so later, I had both of our costumes done. :D
Funny story about that...
