Being great friends, The Netherlands' Crown Princess Maxima and her Belgian counterpart Mathilde are bound to share similar tastes.
At the opening of an art exhibition in The Hague this week, the two ladies - who are regarded as among Europe's most elegant royal consorts - showed just how in sync they are sartorially, stepping out in matching houndstooth coats.
Maxima's version, which she wore over a classic black number, had on-trend, three-quarter-length sleeves, while her friend's more voluminous choice was the perfect cover-up to accommodate a growing bump. Mathilde is expecting her fourth child in the spring.
The pals' co-ordinated look lent an appropriately harmonious note to Tuesday's event, as did their obvious enjoyment of the outing - and each other's company.
