Dude, what's with the outfit?

I'm a bit Spammy McSpammerson lately but...

Is it possible Castiel confused his clothes with someone else's clothes or did he just get tired of looking like a 'Holy Tax Accountant' and thought he'd try the 'Holy Dean Winchester' look instead?



He's even got the layers happening!

I have no idea when this pic surfaced so apologies if I'm way behind the times. :)
