Queen Letizia traveled to Paris today to attend the opening session of the 2016 World Cancer Congress.
The Queen of Spain was seated next to the French President Francois Hollande and Morocco's Princess Lalla Salma, wife of King Mohammed VI for this evening's opening ceremony.
Her Majesty delivered the keynote address at the high-profile event which brings together 3,000 cancer and health experts from 130 countries to discuss and to exchange best practices in global cancer control.
Letizia took to the stage in a chic all-black ensemble, her colour of choice for after-five events.
The Queen of style premiered a tuxedo-inspired jumpsuit by her go-to brand, Hugo Boss. The BOSS 'Duxida' jumpsuit (£480) is a real head-turner with its plunging V-neckline trimmed with a shimmering silky collar. The matching satin belt accentuates the feminine silhouette. It is available to purchase from Hugo Boss stores and online at House of Fraser.
Queen Letizia arrived at the convention center in the French capital wearing a new stone wool cape.
It is the Hugo Boss 'Capina' swing cape, a design she also owns in black.
Letizia accessorized with her black Nina Ricci 'Arc' leather clutch and black Prada Saffiano print patent leather pointy toe pumps.
With her hair swept back into an up-do, Letizia finished the look with her TOUS gold long dangle earrings from the jeweler's 'special jewelry' collection.
