Prabal Gurung's ICB Girl 'Thinks Dirty Thoughts,' Parties All Night Long

Party girls — the ones who rage into the wee hours of the morning, wake up rough, and roll out of bed — were the inspiration for Prabal Gurung's ICB fall 2013 collection, but let us tell you, there was no walk of shame happening on that runway.

"This girl does her makeup in five minutes, runs out the door, had a fabulous all-nighter and still looks gorgeous in the morning," said MAC makeup artist Yadim.

To make the "polished punk" look come to life, Yadim started with MAC's "Feline" Kohl Power Eye Pencil, tracing inside the waterlines and smudging underneath the lashline. Taupe blush, not eyeshadow, gave the eyes a sullen, sexy look. And when it came to mascara — the heavier, the better was his motto, which he applied by moving the mascara wand back and forth, instead of up and down.

Butter London's global color ambassador, Katie Hughes, reflected the same gritty sensibility with matte graphite nails using Butter's "Chimney Sweep" and "Matte Finish Top Coat." (Side note: We've been spotting tons of matte nails on the runway this week!)

"Prabal basically gave me a couple of words that really made it clear what we were going to do," she told us. "He said, 'Girls that think dirty thoughts, they look really chic, but a bit dirty all at the same time.'"

Consider it our goal to look half as cool as these girls the next time we wake up hungover.
