What to be what to be! Cosplay outfit help?!?

Hey guys, Just found out in august there will be a convention in Vancouver,WA. Like literally 1 1/2 hour away from me. I literally have no idea what to wear or who to be. I love all animes. Was thinking black rabbit , or Nike from this world is still beautiful . I'm not into schoolgirl outfits. Unless they are more "showy". I'm not really a conservative cosplayer. I've gone as lulu from ffx before. Tsunade too. Honestly I have a heavier top peice so please no young girl cosplays. Thanks in advance!!!

A vocaloid!!!! Honestly all theyre cosplay are cheap and can be bought in full set for like $140 depending on who you get and which outfit plus theyre always loved so you have a high chance of asking your pic being taken

But if you want flashy and out there then youd have to cross over to the video game world and maybe go with moxxi from the borderlands series or a persona charater sinve they alot of hype for the game being released both can be up in high price but if you have a bugdet of like 250 your fine
