Duchess Sophie could be a vintage star in silhouette-sculpting skirt

The cream-hued floaty number was paired with a khaki slim-fit shirt from Vince and cinched further with the 'Leiva' cashmere blazer from Gabriela Hearst - a sartorial debut for Prince Edward's wife.

The mother of two rounded off her look with the 'Cleo' bag from Sophie Habsburg and a pair of nude leather pumps from Prada. As ever, Sophie's sandy blonde locks were swept off her face in the most elegant fashion and her makeup look created a radiant look.

Sophie's cinched skirt and blazer combo has become her go-to for daytime royal outings. However, the Duchess was seen sporting totally different attire on Tuesday night as she made a surprise TV appearance.

Lady Louise Windsor's mother appeared in an episode of The One Show ahead of the annual Children in Need telethon where she joined 21-year-old Emily, who has cerebral palsy, on the second day of her charity walk.

Sophie wore a pair of dark-wash skinny jeans which were elevated by a luxurious anorak - the 'Technical Lancashire Field Coat in Moss Green' from James Purdey & Sons which retails for £895.

The two-piece number, which retails for £800, was accessorised with the 'Lunatic Caviar' clutch from Sophie Habsburg and the 'Zadie 85' boots from Jimmy Choo.
