My newest costume is Twilight Sparkle's Grand Galloping Gala outfit from My Little Pony: Friendship is Magic. It's actually not finished, although it's technically wearable. I'm not sure if I'm going for the whole weekend or which costumes to bring. I think it will depend on what meetups/photoshoots are going on. I may be wearing Raine, Franziska, or Lyn if I bring multiple costumes. I doubt I'll be able to get another new costume together before Megacon.
Franziska von Karma (Ace Attorney series- older and younger versions)
Lyn (Fire Emblem/Super Smash Bros. Brawl)
Raine Sage (Tales of Symphonia)
Grell Sutcliff (Kuroshitsuji, butler outfit)
Rose Bride Utena (Revolutionary Girl Utena, need new wig)
Twilight Sparkle's Gala Dress (My Little Pony: FiM)
