Sharp, swooping strokes of pink at Dior; tiny, bright green accents at Versace; crisp outlines of tangerine, lemon and chartreuse at Kenzo. No matter where you look, neon eyeliner is everywhere. The fearless trend began back in 2011 during Peter Som’s spring presentation, and now, as we examine Resort 2014, it fights on, revealing itself in the form of a brilliant, incandescent blue against charcoal lids at Chanel.

Not only has this bold look been turning heads on the runway, it is also popping up in editorials — most recently in the June issue of Vogue Netherlands. Against slicked-back hair, oversized futuristic hoop earrings and smoky eye shadow, model Karlie Kloss (shot by Hans Feurer) shows off amethyst eyeliner by YSL — drawn in short, thick lines from the corners of her eyes to the tips of her eyebrows.

For those celebrities who have been daring enough to try it, neon eyeliner has made its way off the runway. Solange Knowles, for example, donned what has become one of our favorite interpretations of the look. During a spunky performance in New York City, Knowles flaunted an electric blue version — a look nearly identical to those cool curves of cerulean seen at Michael Kors’ S/S 2013 presentation.  

Though we have seen plenty of variations over the past few seasons, the look still has a great deal of unexplored potential. Also “in vogue,” is the super-geometric eyeliner seen at Preen, Mary Katrantzou, Aquascutum and Erdem. Over the next few seasons, we expect to see a fusion of the two: neon eyeliner merged with increasingly inventive designs and shapes. Either way, we hope this eccentric look will stick around.
