Lavender Dream

Vivienne Westwood's ateliers created Perry's short-sleeved lilac jacket and matching skirt using a soft leatherette taken from the archives for the royal occasion. The "Teenage Dream" singer wore a silk flower pinned to her lapel and a dramatic headpiece adorned with "merry widow veiling" to complete the ensemble, which included Vivienne Westwood's Granny Frame Pearl handbag, elbow-length gloves and Three Row Pearl Bas Relief choker.

Royal Hue

Since ancient times, purple has been associated with royalty. It's no accident that the velvet linings of St Edward's Crown, the Imperial State Crown, and Queen Mary's Crown are all dyed the same distinct shade. Queen Elizabeth II made purple her official coronation color in 1953. Although Perry's taking on the regal hue was a pale pastel, her homage seemed like a subtle nod to the day's festivities without rubbing the royal apologists the wrong way or giving away too much of Perry's kitschy charm.

Westwood Style

In addition to perfecting the royal look, Perry also paid tribute to the UK by wearing Vivienne Westwood- most notably her pearl-string orb choker – a signature piece for the designer. As a renowned British designer who passed away in December 2022, Westwood had a long and successful relationship with the British royal family, beginning in 1991, when she was awarded the prestigious British Designer of the Year award and was invited to Buckingham Palace to accept it. In 2015, Westwood dedicated her autumn/winter collection to the now-King Charles for his environmental initiatives. Per the Guardian, she wrote at the time: "I want to pay tribute to Prince Charles. If Prince Charles had ruled the world according to his priorities during the last 30 years, we would be alright and we would be tackling climate change." Princess Eugenie, Charles' niece, also supported the late punk fashion designer, even wearing one of her designs at Prince William and Kate Middleton's wedding in 2011.

"A very kind soul"

Prince Charles announced Katy Perry would become an ambassador for the British Asian Trust at the Banqueting House in London in February 2020. In a statement, the British Asian Trust announced Perry would play a specific role: for the next five years, she'll work with the organization's Children's Protection Fund, which fights child trafficking. Natasha Poonawalla, an Indian billionaire and philanthropist, chaired the fund, pledging to donate more than £1 million. "India has always been a place I have a magnetic connection with," Perry said in an Instagram post. "Every child matters and has the right to basic human needs.

Her connection with Charles already existed. They met in November 2019 at an event hosted by Poonwalla to celebrate Charles's birthday in Mumbai. While the singer was in town for a concert and a Vogue India cover shoot, the royal visited the country on an official mission to promote sustainability. According to Tatler, Perry introduced Charles with her trademark playful humor, calling him a "very kind soul." "[He's] so kind that he talks to his plants," she said. "He asked me if I could sing to his plants. And I will, in the future. You have my word, sir."

"Baroque grandeur"

Perry, who recently wowed fans at Westminster Abbey in her bespoke lilac suit, leaned into the gilded mood of the overall Coronation celebrations by wearing a custom Vivienne Westwood gown during her performance at the Coronation Concert. With its corseted 18th-century silhouette and gold metallic leatherette, it is said to "exude baroque grandeur," according to the brand. In particular, the draping is based on a bridal look from the British house's spring 2006 Gold Label collection.

A "Roar-ing" good time

Princess Charlotte, who happily sang along to Katy Perry's "Roar" while Prince George waved his Union Jack flag in time to the beat, was among the many fans of Katy Perry's performance at Windsor Castle. Perry, however, dedicated her song "Firework" to King, thanking Him for "bringing out the firework in so many young people" through his charitable initiatives.
