International Wrinkled Shirt Day

_{International Wrinkled Shirt Day is celebrated annually on December 20. The holiday’s name might seem silly, but it actually has a serious goal to help people around the world become more environmentally conscious. International Wrinkled Shirt Day was launched in 2019 by several Argentinian civil society and non-governmental organizations ‘Red Solidaria’, ‘DondeReciclo.org’ and ‘Mundo Invisible’.}
