Intentional clothing choice. It's a tighter version of what Iori has in King of Fighters, www.fightersgeneration.com/np8/gifs/iori-classic-kof13stance-2.gif
Im curiouse what that elastic pixel that connects the bottom of the pant legs together is for? Was that an accident or an intentional clothing choice?
Oh okay that makes sense now. I think its a cool addition now that I understand what it is.
