Queen Letizia was on hand this evening to present two Spanish children/youth literature awards, 'El Barco de Vapor' and 'Gran Angular'.
The annual awards in Madrid are organised by the SM Foundation whose goal is to promote youth-focused books and reading.
Her Majesty looked chic in black and white separates for the occasion.
She debuted the Hugo Boss 'Juxtiny' blazer (£399) - a tuxedo-inspired jacket crafted in a wool-blend. This single-breasted design is detailed with satin at the peak lapels and collar. This blazer is finished with fabric-covered buttons at the centre front and cuffs. The style also comes in black.
Underneath the blazer Queen Letizia wore a white satin lace-trimmed camisole, first seen during last year's State Visit to Peru.
She contrasted the white with a new pair of black silky trousers which I have not been able to identify.
We saw the return of the Bottega Veneta's iconic 'Knot' clutch and Manolo Blahnik 'Gotrianc' Slingbacks 105 heels.
Queen Letizia accessories with her modern circles link earrings which date back to 2008, and the mystery gold open oval ring she debuted yesterday.
