Prince William and Kate Middleton made our morning with their adorable family Christmas card for 2017. It features Prince William, the Duchess of Cambridge, Prince George, and Princess Charlotte smiling wide as they posed for photographer Chris Jackson, but there’s one detail in particular that eagle-eyed fans couldn’t help but notice: the color scheme.

Though it was noted by the Royal family that the shot was taken earlier this year, it didn’t stop followers from speculating about whether or not the lovely shade of blue the family chose for the shot might be a not-so-secret hint that she’s expecting another baby boy come April.

The photo’s Instagram post was flooded with similar comments, reading, “The Duchess [wears blue] around the time [she hits] four months of pregnancy, for me, that is a hint,” and “That’s a lot of blue. Are they announcing a boy?”

As it turns out, there might be another reason for the color choice. Middleton’s suit, designed by Catherine Walker, is actually not unlike those worn by Princess Diana, who was also a fan of Walker, in her day.

The ensembles are also ones the family has worn before. Middleton was photographed wearing the same suit during an appearance in the Netherlands back in 2016, while Prince George was shot wearing the same adorable outfit for his official fourth birthday portrait, which was released back in July and taken at the end of June. As for Princess Charlotte, she was snapped in HER blue ensemble while exiting a plane in Berlin.

While it’s not the first time Middleton, 35, has been photographed wearing shades of blue since since announcing her pregnancy (you might recall her gorgeous ice blue gown that reminded us of Queen Elsa from Frozen last month and the light blue Temperley London sheath she wore for her first public appearance post-pregnancy announcement back in October), she’s also worn shades of pink, like the Orla Kiely frock she donned for her second appearance.

In conclusion? It’s likely much ado about nothing, but it’s still fun to speculate over, no?

Do you think the photo acts as a sex reveal? Let us know @BritandCo!
