Emily Mathers' 2017 Sombrero Festival shirt design highlights the charm and heritage of the Charro Days celebration. Featuring children dressed in traditional Mexican and American outfits, the design symbolizes unity and cultural pride. The sombrero takes center stage, surrounded by vibrant red, green, and gold accents inspired by festive decorations. A playful addition of a piñata and a kitten adds a touch of joy and innocence, making this design a heartfelt tribute to the festival's family-oriented spirit.
