This Friday (24 April) is Fashion Revolution Day, when fashion brands globally will be asked to be more transparent with their supply chains.

The public are being urged to ask brands #whomademyclothes on social media, and so encourage them to monitor their supply chains. Events and PR activity on the day will place pressure on brands to map-out their entire supply chain and find out where their garments come from. It will be an excellent opportunity for brands to communicate the progress they are making in this area and will act as a reminder for brands who are less active in this area that there is a demand for greater transparency.

Transparency in the fashion industry has become a key concern in recent years, particularly following the Rana Plaza disaster in 2013. Fashion Revolution Day marks the second anniversary of the disaster in Dhaka, Bangladesh, when 1,133 people were killed and over 2,500 injured. One in six people work in the fashion supply chain, it is the most labour dependent industry worldwide. For those who make the clothes in developing countries, working environments are frequently unsafe and poorly paid.

Orsola de Castro, co-founder of Fashion Revolution says, "We believe knowing who made our clothes is the first step in transforming the fashion industry. Knowing who made our clothes requires transparency, and this implies openness, honesty, communication and accountability. It’s about re-connecting broken links and celebrating the relationship between shoppers and the people who make our clothes, shoes, accessories and jewellery – all the things we call fashion."

Fashion Revolution's hashtag was the number one global trend on Twitter last year and this year events are being organised in 68 countries around the world.
