Costumes and Outfits

So what exactly do you like to wear? I'd like to make up an outfit but I feel like i don't even know where to begin.I dress so normal irl in civilization. Don't get me wrong though; its not my primary reason for existence. But, it still sounds fun you know. A chance to express beyond my normal wardrobe of black and grey. I'm a guy as well. Not that that matters so much, but any costume ideas or suggestions would be more geared towards that. Thanks friends.
