I will either be Rainbow Dash or Fluttershy next year. They're both really awesome, except there are the pros and cons to them.
Rainbow Dash
Pros: I plan on a Punk!Rainbow Dash, which will be fun to plan and design. Rainbow is also a really colorful character to recognize and being her character for some of the con will be really fun.
Cons: With my main design to do, there are EXTREMELY difficult parts to it. I want to make a small bag with RD's cutie mark, which will be a pain in my a** to find the right fabric for it. For the shoes, I want to find a pair of plain white Vans or Converse so I can color rainbow on them, but I don't know where I can find cheap ones. And last but not least, I'm going to have to try and find a WIG and a TAIL cheap, but great quality.
Fluttershy
Pros: Fluttershy is my favorite and her cosplay will be really easy to do; I already have an outfit or two planned out and it'll be easy for me to make and finding a wig and a tail won't be a problem.
Cons: I feel like Fluttershy will be way too simple for me to do (but yet again, I want to do a SIMPLE cosplay and a complicated cosplay for next year.) which is why I considered Rainbow Dash over her.
