"Capitol TV" spoke in regards to President Snow and his stylists regarding the iconic look.

President Snow has a variety of teams devoted to his cosmetological needs. The wardrobe team, lead by famed stylist Juliana Rydell, is in charge of designing, procuring, and pressing and President Snow’s suits for every occasion; staying on the cutting edge of Capitol trends to ensure Snow is on point; polishing Snow’s lapel vase, and of course, selecting his signature white rose.
The hair and makeup team, lead by Trivalda Enfario (pictured here), make sure every hair is in its place (literally). President Snow has a strict daily regimen consisting of a haircut, beard trimming, manicure, and teeth whitening. And take it from us, their efforts do not go unnoticed. Even looking at President Snow close-up, his perfection is almost astounding. In a room of even the most prestigious individuals in the Capitol, there’s no doubt who transcends them all.
