1. First, decide who you want to cosplay. Do you just want a costume to wear around town, for fun, or do you want to wear it to an Anime Convention or other big event? If it's your first time cosplaying you may want to choose a character with a simpler outfit. However, if you do not mind strange stares and/or possible harassment, then feel free to go all out. For the latter, any costume will work, although unique costumes are more likely to stand out.
