1) Uhm...I would love to cosplay as Casca in her Hawk uniform, but then I would have to cut my hair again and I look really bad in short hair. Course it would be fun to Cosplay Puck too or Roshinu.
2) Uhm...I look like Schierke or Rita.
I will be cosplaying Casca in the monk robes at the end of the month though I'll probably look horrible...gotta get used to wearing contacts again :-/
As for Japanese Cosplayers...take the pictures with a grain of salt. A number of companies sell already made costumes for cosplayers in Japan and can be found advertising in magazines. So it's anyone's guess it those are original works or purchased. What impresses me more is how they get a group together for it...
Also, for Naked characters like Slann, wear a transparent body suit. A-kon a few years back had a woman cosplaying as Kekko Kamen(Sp?) and All she has was the mask, boots and a fleshtone bodysuit.
