On Thursday, Queen Mathilde first hosted a roundtable discussion about the mental health issues that can occur at a later age, such as Alzheimer's.

Afterward, Queen Mathilde attended the event “Sustainable Value Chains: from legislation to action” in her role as an Advocate for the United Nations Sustainable Development Goals.

The event aims to discuss how companies, NGOs, and public institutions can complement each other to set up value chains that protect human rights and the environment, and thus contribute to sustainable development.

Queen Mathilde wore a new Giorgio Armani jacket with black trousers, black pumps, and her Girogio Armani clutch (with thanks to ModeKoninginMathilde). She also wore her Rolex watch.
