Marc by Marc Jacobs Spring 2013 | Runway

Marc Jacobs's Spring 2013 mainline collection may have been all about restrained sensuality, but his secondary line was clearly all about fun. As in the thing that girls just wanna have. It came spelled with a capitol F, and it touched everything from the pastel striped runway to the 1982 electropop playing on the speakers to the Cyndi Lauper scarfs wrapped atop the models' heads.

As for the clothes, well, they were pretty jazzy too. Lots of wacky geometric prints, riotous hues, and plenty of washed-out denim and stripes. On boxy tops, shoulder-padded blazers, flouncy skirts, and peg-leg pants — which came tight-rolled at the ankle, remember that? — it made for a pretty energetic offering. Pile it on, and turn it up, the designer seemed to be saying. And really, why not? There's nothing much more fun than that.
