Okay, uh.....Pyrhha as Sailor.....I think Jupiter....Ruby as Annie from League of Legends, Penny as a Minecraft Creeper, Ren as Ash Ketchum of Pokemon, Sun as Naruto, Weiss as none other than Hatsune Miku, I wanna say Velvet is dressed up as Belle from Beauty and The Beast, but I'm not quite sure....I'm also tempted to say Yang is dressed up as....I believe her name was Mami Tomoe or something....and everyone else I can't figure out. Unless Neptune is dressed as one of the guys from that anime about the almost-always-shirtless swimmer guys.
