What is International T-Shirt Day?
International T-Shirt Day is held every year on June 21 and is observed worldwide. The day celebrates one of the most iconic and widely worn garments across the globe: the T-shirt. It honours the simplicity, versatility and personal meaning that this item of clothing can carry.
The day also marks the beginning of the T-shirt season in the northern hemisphere. From personal statements to fashion staples, the T-shirt plays a central role in wardrobes everywhere.
History and Origin
International T-Shirt Day was first launched in 2008 by a German company specialising in custom clothing. It started as a small celebration in cities like Berlin and Boston, but quickly gained popularity in other European capitals and beyond. Since then, the day has been marked by design contests, swap events and public showcases.
The date of June 21 was chosen for a simple reason. It is the longest day of the year in many parts of the world, and therefore the perfect time to celebrate summer’s favourite item of clothing. It is now used as a platform for both fun and creativity within the fashion and DIY communities.
