Roman is a member of the popular kids at Cavendish, and his hair, makeup, and nails reflect this status. Throughout season four, they're continuously playing with glitter, graphic eyeliner, and fun nail art. "Felix was already wearing nails when we met," Bilverstone says. "He brought that part of himself to the character of Roman."
But realistically, Bilverstone's team couldn't produce an entirely different manicure every time they shot a new scene, so they needed a workaround. They ended up having five different sets created by social-media-famous manicurist Fuego Nails so they could pop the tips on and off as needed.
Another element of himself that Felix brought to the character is his tattoos. "All of the tattoos that you see on Felix are his own," Bilverstone says. The only design they changed is the "2001" written across their chest in big numbers, signifying their birthdate. "We couldn't keep that, because Felix is playing someone younger." They brainstormed ways to transform the numbers into a different year that would make more sense before Felix was hit with an idea. "He was just like, 'Why don't we make it say Abbi? And it was the most obvious thing."
