I am fairly new to cosplay, but I really want to do a lighted costume. What would be a good easy one for a newbie? I am a girl, and I prefer superhero costumes but I wouldn't mind branching out. I really love being as accurate to the original design as possible, so having light be a part of that would be perfect.
