The list author says: "I encourage all you girls to wear any of these nerdy, I mean sexy costumes. Your super dorky, I mean cool boyfriend will love you for it. Most of these are Rubies brand, not always the most authentic, I recommend building your own. And as always check those reviews before purchasing. Also, my secret to cos-play costumes is, the more you already look like your character the better your costume will look. Amazon doesn't have everything, of course...
