Here is my situation. My primary plan is to cosplay as a Scout from Team Fortress 2. However, I am wondering if it is considered taboo to be cosplaying as a character that isn't in the "Anime/Manga/Japanese video game" style. I do have a back up plan: Kamina from Tengen Toppa Gurren Lagann, but I don't want to commit to this significantly more difficult costume without knowing the Scout idea is no good. I am requesting some of your wisdom for this predicament.
Note: this is my first Otakon visit (3rd convention visit overall)
