Prediction: This Collection Will Be Your Spring Urban Jungle Uniform

We've written about the lovely ladies behind William Okpo before, but one glance at the brand's latest lookbook proves these sisters are well worth stalking. Darlene and Lizzy are the new darlings of the New York style scene thanks to their elegant and architectural clothes (you've ogled them at Opening Ceremony, no doubt), which blend their Nigerian heritage with an urban American edge. Their spring '12 offerings include plenty of maxi silhouettes with unexpected elements—sheer and opaque fabrics create a sexy, almost color-blocked effect, plus there's plenty of button-ups and slim-cut pants to feed your mix-and-match desires. And while we're not sure you'll be catching us rocking a drop-crotch jumpsuit anytime soon, we're more than a tad obsessed with that unique pair of overalls and all of those gorgeous, asymmetrical cropped tops. Trust us, just click through to check out the lookbook for some major inspiration to switch up your silhouettes. If you're still not obsessed (really?), check out this behind-the-scenes video from Arcade 44 to see how the collection came together. Le sigh, maybe if we wish really, really hard, it'll suddenly be June instead of November so we can strut our stuff in these outfits.
