I NEED COSPLAY HELP!?

Hello there, I'm going to fanexpo this year, and need help picking a cosplay to make. My previous cosplays have been Kagome (from Inuyasha), Robin Sena (from Witch Hunter Robin), Misa-Misa (Deathnote) and Sailor Mars. I am taller than average, though not super tall. I have long blonde/light brown hair. I wear glasses, but have contacts if need be. I have a slender build, but I'm not rake thin. I own a long-ish black wig, but I don''t think I will be dying my hair to fit the character. Either a wig or my natural hair. I am excited to make something again this year!!! :) Also, I don't mind big swords or props, I can make those. Please leave any suggestions! :) :) Hope to see you there!
