Katy Perry arrived at King Charles III’s coronation at Westminster Abbey in London on Saturday morning to see the new monarch be crowned.

The “Daisies” singer, 38, chose a beautiful lavender suit set by Vivienne Westwood, pairing a knee-length dress with a short-sleeved blazer and opera-length matching gloves.

Perry, who briefly struggled to find her seat inside the abbey, topped the look off with a matching fascinator, pearl earrings, a Westwood-designed white purse and a pearl necklace ($430).

The choice of both color and designer, of course, pay homage to British culture, as purple is historically associated with royalty and Westwood was from the United Kingdom.

The designer, who died in December 2022, was known as the “high priestess of punk” and memorably revealed that she was not wearing any underwear when she received the an Order of the British Empire (OBE) from Queen Elizabeth II in 1992.

Let’s hope that Perry keeps her undergarments (or lack thereof) under wraps during the history ceremony, as the “American Idol” judge is set to perform at the coronation concert Sunday night with co-judge Lionel Richie and Andrea Bocelli.

While the two are away, Ed Sheeran and Alanis Morissette will take over their responsibilities on the ABC singing competition series, which has seen Perry steeped in controversy as of late.

Perry — whom Charles named as an Ambassador to the British Asian Trust in 2020 — was seen arriving with British Vogue editor-in-chief Edward Enninful, while other attendees at the historical event include Richie, 73, as well as first lady Jill Biden and her granddaughter.

Last week, the “Dark Horse” singer revealed that she will be staying at Windsor Castle during her visit, saying, “I’m really excited. I might be posting a lot because I’m gonna be in a castle.”
