Don't forget the feet! You can tell by this pic better that color-blocking shoes are so IN. I love this look! They're versatile and the colors just work. Of course they'd look great with black, but why not pair them with an outfit similar to the first picture? You're tying the blue in the pants and shoes -- the other colors are just fun additions that add flair to the outfit. You don't have to be "matchy-matchy" when wearing outfits!
Use color in fun ways. If you see stickers or something else you like the colors/pattern of, translate that into an outfit! :) The possibilities are endless.
