NEW YORK – Neon is a fashion trend that might be best suited to the cool kids — or real kids.

Unlike so many looks that trickled down from designer runways to mass retailers and into teenagers' closets, the almost electrifying shades of pink, green, yellow and orange have been hanging out in high school hallways for a while. And they're back again for the new school year.

"Teens stayed with neon because for them, it's so easy to wear. It taps into youth, emotion and standing out, which they like doing," says Seventeen senior fashion editor Marissa Rosenblum.
