Kensington Palace trio were meeting on Tuesday, January 17th, to prepare for their big project of the year. At a conference at the Institute of Contemporary Arts, Princes William, Harry and Duchess Catherine defended "Heads Together," a collective of associations whose three crowned heads were originally in sight of the London Marathon.

"Heads Together" is the charity supported this year by the London Marathon in the heart of the British capital. On this occasion, The Duke, Duchess and Prince Harry presented their initiatives to leaders of the whole of British society, media companies or new technology, through the business community and the voluntary sector, to rally them to their project .

"Heads Together" is a federation of eight mental health charities, launched in March by William, Catherine and Harry, to share efforts to encourage people to talk openly about their mental health problems and search for help. For this occarsion, the Duchess debuted a new dress by one of her favorite Canadian fashion designer's, Erdem 'Evita' black lily collage dress, accessorized with her cranberry suede Mulberry 'Bayswater' clutch bag and burgundy Tod's fringed leather pumps, completed the look with her Oscar de la Renta hammered gold-plated faux pearl earrings
This new association is part of the Duchess of Cambridge's long work to raise awareness of mental distress. Catherine was already the godmother of one of the eight associations, Place2Be, which accompanies more than 75,000 children victims of psychological problems in school.
