Why vintage wins: buying a vintage t-shirt instead of new saves 2.5kg of CO2, equivalent to charging a smartphone 300 times. A new pair of jeans takes 7,500 litres of water to make, enough to hydrate a family of four for nearly 7 years. A new knit jumper uses over 1,200 different chemicals in production. Ireland disposes of over 225,000 tonnes of textile waste every year, out of 1.2 million tonnes worldwide.
