Monaco’s cutest royals showed their colors Friday evening to mark the end of summer.

TwinsPrince JacquesandPrincess Gabriella, 3, accompanied parentsPrince AlbertandPrincess Charleneto the principality’s traditional end of summer picnic (or U Cavagnëtu), both dressed in traditional costumes.

Gabriella, wearing the bright red and black of a palladian dancer, took centerstage alongside her brother during the royal family’s two-hour-long attendance.

It was the first public outing for the family since the return fromtheir ‘far away’ family vacation— a trip toTahiti’s eco-centric Brando resort, where Princess Gabriella picked up a few dance steps from fellow island visitorLady Gaga!

“[It] was a very, very, very beautiful evening,” one picnic attendee tells PEOPLE. “The children clearly enjoyed themselves with their cousins around them and, the music and food.”

“They’ve grown so much over the summer,” notes another resident. “What’s truly amazing, really special, to see is how attached they are to one another. How attentive Princess Gabriella is to her brother.”
