I probably have way too many black and white striped things in my closet. I mean, it's terrible. (I've actually talked about it before.)
Black and white stripes in a room can ground the space and add a bit of graphic interest. Plus, they're great because they play nice with others. And that myth that you can't put black and navy together? Call me a Mythbuster. Totally go for it, dude. Bold color combinations can make a room amazing.
