On Saturday, Hereditary Grand Duke Guillaume and Hereditary Grand Duchess Stéphanie attended the ' All Together' concert hosted by the Fondation EME to mark their 15th anniversary. The Foundation promotes the virtues of music – in the form of concerts or projects – to stimulate the well-being of elderly, disabled, sick, excluded, vulnerable, or disadvantaged people.

To mark the anniversary, the Hereditary Grand Ducal Couple has also announced that they have become Patrons of the Foundation.

Hereditary Grand Duchess Stéphanie wore a Scapa suit with Salvatore Ferragamo pumps, her Polène bag, and her Chaumet ring.
