Kate Middleton twins with Crown Princess Victoria in Zara blazer

Royals love a blazer bargain.

The Platinum Jubilee parties are over and it was back to work for the Duchess of Cambridge today as she stepped out in a beige blazer from Zara ($70) to visit a family charity — just a day after Sweden’s Crown Princess Victoria wore the same jacket in green.

The piece features shoulder pads and inverted lapels for a clean look, perfect for carrying out royal duties — and each of these future queens styled the blazer in their own, quite different ways.

Middleton, 40, wore the jacket with a simple white tee shirt and previously worn wide-legged black trousers by Roland Mouret to visit London’s Little Village Brent, a “baby bank” that provides families with essential supplies such as clothes, toys, and baby supplies for children up to age five.

She kept her accessories minimal for the all-business look, adding just a pair of Kiki McDonough citrine drop earrings ($689) that she’s worn on many occasions over the years and carrying a Massimo Dutti woven clutch bag ($179).

The visit marks her first public appearance since the Platinum Jubilee festivities when the duchess wore a series of stunning looks to celebrate the Queen’s 70 years on the throne.

The royal has definitely been on a beige kick lately, whether it was wearing a Self-Portrait dress ($585) for a joint engagement with Princess Anne or a Reiss blazer ($360) to visit Ukraine aid workers.

As for Crown Princess Victoria, the heir to the Swedish throne chose the green version of the same blazer while on an official visit to The Netherlands yesterday.

The 44-year-old stuck to her normal bold style choices by going in a monochrome direction, pairing the jacket with matching high-waisted trousers ($50) from Zara.

She kept the green theme with a favorite pair of suede pumps by Malene Birger and added a white pussybow blouse along with a tan bag ($1,234) by Susan Szatmary.

The chic topcoat is selling out quickly, but not to worry: It’s available in three other colors, including a sassy red and bright blue.
