The Monaco Grand Prix has long been an opportunity for Princess Charlene to show off the most glamorous garments in her wardrobe.
However, fans could be forgiven for doing a double take on Saturday when the Monagasque royal, 47, stepped out in the most unexpected footwear.

Her chunky-soled tan kicks were teamed with a pair of wide-leg black trousers and a white blouse with printed pannelling down the front – the 'Guepards et Palmettes Painter Blouse' from Hermès.

The princess - who is a keen sportswoman herself, having competed in the Olympics as a swimmer - has been on a number of sport-centred outings recently.
Earlier this month, the Zimbabwean-born royal made an appearance at the award ceremony during the race of Monaco E-Prix round seven.

She had switched up her look entirely from the grey double-breasted Crisoni suit and white Francesco Russo heels combo she sported on day eight of the Rolex Monte-Carlo Masters in April.
