Princess Leonorof Spain was all business on her 18th birthday — in the new go-to royal uniform!

The future queen of Spain wore a white suit toswear allegianceto the Spanish Constitution in Madrid on Tuesday, a significant step on her road to the throne as she turned the age of majority. The Princess of Asturias swept her hair into a low ponytail, providing a good look at her newly awarded government medals and the Collar of the Royal and Distinguished Spanish Order of Carlos III.

As she continues to define her royal style, Princess Leonor’s latest fashion statement took a nod from modern royal women — and is officially the new princess uniform. While previous generations of royal women rarely deviated from dresses and skirts (aside from her riding breeches,Queen Elizabethwas almost never photographed wearing pants during her record reign!), power suits are a fresh choice for modern royal duty. White might be the hottest hue, asKate Middleton,Meghan MarkleandQueen Letiziahave all recently suited up in the shade!

“I think it marks a new era in her royal life,” Bethan Holt, fashion director at theDaily Telegraph,previously told PEOPLE. “It shows her confidence is growing and that she’s willing to take more risks and do something that might not have come naturally to her.”

“She’s transforming before our eyes. She might not be able to say to us, ‘Look, my life is now completely different, me and my husband are one step closer to the biggest job of his life,’ but she is saying that through her fashion choices,” adds Holt, who authoredThe Duchess of Cambridge, A Decade of Modern Royal Style.
