The Tonight Show Starring Jimmy Fallon is renowned for its extravagant and eye-catching Christmas sweaters, and in an exclusive sneak peek, costume department head designer Mario Martines reveals the intricate process behind creating these festive garments.
Martines shares that the idea for the Christmas sweaters starts brewing immediately after the New Year, with him sketching out initial designs which are then elaborated upon with his dedicated team throughout the year. The show’s 12 Days of Christmas Sweaters tradition has become a fan-favorite, with each year’s creations becoming more elaborate and extravagant than the last.

Initially, the sweaters were simple and often vintage finds, but Martines saw the potential for them to become something more. He meticulously selects the base materials, considering everything from colour to texture, to transform them into festive works of art.
One of this year’s standout pieces is a Christmas Carousel sweater that lights up, inspired by a detective show Martines watched on Netflix. The creativity and imagination that goes into each sweater design is truly remarkable, with Martines drawing inspiration from a variety of sources, both conventional and unexpected.
Every night during the 12 Days of Christmas Sweaters segment on the show, Jimmy Fallon presents a sweater to a lucky audience member whose seat number is drawn from a Santa hat. The joy and excitement of being able to take home one of these unique creations adds an extra layer of magic to the holiday season.
Martines reflects on his years of designing these special sweaters, sharing that he often wakes up in the middle of the night with new ideas. His ability to continue innovating and surprising audiences year after year is a testament to his passion for his craft.
Despite more than a decade of creating these festive masterpieces, Martines still finds joy in seeing his creations come to life on the show and bring smiles to both fans and Jimmy Fallon himself. Each sweater is a true work of art, reflecting Martines’ unwavering dedication to making the holiday season a little brighter for everyone.
As the holiday season approaches and Christmas cheer fills the air, the intricate process and creativity behind The Tonight Show’s Christmas sweaters serve as a reminder of the magic of the season. The tradition of spreading joy and festive spirit through these unique creations continues to captivate audiences year after year.
