Loud Shirt Day is celebrated on October 18th and focuses on supporting children with hearing loss by encouraging participants to wear their brightest and boldest clothing. The event aims to spread joy and raise awareness, transforming offices, schools, and communities into vibrant displays of color. Typical customs include wearing eye-catching outfits, hosting dress-up days at work or school, and sharing stories online to promote the cause. Participants are also encouraged to donate to organizations that assist children with hearing challenges. The initiative originated in South Australia and has since expanded to involve various groups across Australia and New Zealand, emphasizing the importance of inclusivity and support for families affected by hearing loss.
