To pull this trend off and prevent your home from looking like a gothic circus tent, I think you have to follow the lead of the designers above and pick one striped pattern to focus on.  Don't add a lot of competing colors.  Pick a small nook or a feature wall to draw attention to with the wallpaper instead of doing a large space.  In the top bedroom you have just the black and white wallpaper on the wall behind the headboard, and the rest of the room is filled with neutrals.  It looks so incredibly fresh and visually interesting to have that bold graphic stripe breaking up the white walls.  Sigh.. I love wallpaper.  I can't believe I am saying it; I have tried and tried to tell myself I don't really love wallpaper, but I do.  I officially give up all attempts to resist it... I love it.

If you don't love wallpaper, then you could always do a black and white striped rug.  Rugs are always a great way to add color or a bold statement without going overboard.  And you don't have to scrape rugs off of your wall when you decide that you actually hated wallpaper and what the hell were you thinking?

And just look to Kate Spade if you doubt it, but mixing black and white with pinks or golds (or both) can be incredibly feminine.  I kind of really dig the idea of mixing black and white stripes with blush fabrics.  I can imagine that would even look good together in clothing.  Probably someone else's fashion blog is doing it right now, hah.
