So I'm going to ACen in May with my cousins and friends, but I've run into a bit of a problem. The other cosplay plans I had (Marceline the Vampire Queen, Appledash, and Growlithe) are now unattainable. I don't have the time or skills to make Marceline's bass, and I really don't want to have to do the face/body paint. I no longer have the blonde hair for Appledash and Growlithe, and I don't want to have to buy another blonde wig (I already have two, but neither are the type of blonde I need). So I talked to my cousin, and she suggested sticking with MLP FIM, because the outfits aren't set in stone, so I don't have to go out and buy expensive custom made costumes. She then suggested both Fluttershy (because apparently I have her personality) and Rainbow Dash (because she's one of my favorite characters). I love both ideas, but I'm not sure which I'd be able to pull of better. For Fluttershy, I was thinking a flowy pale yellow dress (like, a sundress almost) with a light pink t-shirt underneath. I would easily be able to fashion some wings and pony ears, and I've found a very good quality pale pink wig (it's long and semi-curly) for a very good price. For Rainbow Dash, I was thinking a white tank top, a blue hoodie with her Cutie Mark on the back, jean shorts with her Cutie Mark painted on them, blue (or red) high-top converse, goggles (to be used as a headband), and of course a rainbow wig. The only issue with that is that the only website I can order things from is Amazon (my mom doesn't trust any other website) and they don't have any good quality rainbow wigs. So I'd probably have to get a white wig and use the sharpie method. I've never done that before, but I heard it's very time consuming. So I need some opinions. Would I be better as Fluttershy or Rainbow Dash?
Here's a pic of me, if it helps:
