For me, no outfit is complete with something a little tough looking. That perfectly proper look may work for some, but I always find myself intrigued by something that's a little well...bad. Applying this to the home, I love infusing elements that make you look twice like a series of ski mask outlines over a classic couch or a skull printed pillow. File under rough.
