This hackathon proposes to gather several complementary ecosystems for a day: the world of images (photo, video, art direction, drawing, painting), the world of influence on social networks, the world of eco-luxury, eco-design and the world of sustainable development and preservation of natural resources, in a day that proposes to take up several challenges such as: how to protect your skin and hair ? How to make the right decisions to have a conscious wardrobe ? What must the fashion industry do to become more sustainable, more responsible, especially in terms of water pollution? How can we design here and produce elsewhere, while at the same time managing to guarantee decent jobs? The intention is to start the day with these challenges, to use open innovation methods to tackle them, to continue with the organisation of a fashion show, and depending on the state of progress, to end the day with a photo shoot.
