Editors, models, and bloggers are all running from show to show [1] throughout New York Fashion Week, but in our opinion, no one's hustling harder than the professionals. Makeup artists, nail technicians, hairstylists, and estheticians [2] wake up superearly, scarf down breakfast, and head out into the blustering cold with their kits. They bravely take on 18-hour (or longer!) work days doing what they love — then finish their nights partying with supermodels.

One such example is Maybelline lead artist Grace Lee [3], who took over the POPSUGAR Beauty Instagram account [4] on Friday, Feb. 12 during Fall 2016 Fashion Week. She shared a glimpse into her life through our feed, including the makeup test for the Public School show and the star-studded Maybelline party. Spoiler: Gigi Hadid makes an appearance! Read on to see what it's really like to be a makeup artist during Fashion Week.
