We knew something was in the air when Alexander Wang, king of murky tones and dark lipstick, threw caution to the wind and sent out a collection of stark whites, punctuated by metallic pastels with nary a shadow in sight. What could have been a runway anomaly has quickly transformed into spring’s biggest mega-trend, steamrolling through the catwalks—and we haven’t even gotten to Paris yet.

Following Wang, Marc Jacobs took a break from his trusty neutrals to send out an ode to Donna Summer and Studio 54, complete with lacquered red lips and a mash-up of seventies tones, taking a cue from YSL and Sonia Rykiel.

The English took their own quirky approach with Christopher Kane’s acid color-blocking looking like tripped-out grannies, but our hearts are with Erdem’s garden of neon hues in full bloom.

At Gucci, Frida Giannini delivered a fringed and beaded collection that would have given Tom Ford a run for his velvet loafers, all in stunning saturated hues. Raquel Zimmermann in orange, turquoise and purple said it all. At Fendi, Karl opted for monochrome jumpsuits so bright the models needed shades—in color, of course.

But leave it to Miuccia Prada to hit the trend into the stratosphere. Her Carmen Miranda Latin explosion was a Technicolor extravaganza, with tropical hues of every possible permutation, even fluorescent fur stoles. Call it cosmic convergence, a new optimism, or simply a change in the guard, but we suggest you start putting those blacks back in the crypt and boning up on your Pantone color chips.
