LONDON — King Charles III’s historic coronation ceremony at Westminster Abbey on Saturday saw a plethora of royals, heads of state and celebrities wearing pastel colours.

The shades are an obvious selection for an historical occasion like that, based on Bethan Holt, fashion director at Telegraph, and the creator of “The Queen: 70 Years of Majestic Style,” and “The Duchess of Cambridge: A Decade of Modern Royal Style.”

“They’re soft, pretty, and unobtrusive, which is ideal in the event you’re certainly one of the hundreds of guests at an event with so many high-profile attendees. Pastels also look very beautiful together – no clashing, only a soft and sweet spectacle,” Holt noted.

“We’re at the peak of spring, too, which is the season when pastels come into their very own – they might have looked much more lovely if the weather had played ball.”

Indeed, similar to at Queen Elizabeth’s coronation 70 years ago, the weather was uncooperative, with dark skies, drizzle and occasional rainshowers.

In Holt’s opinion, standout pastels included the Claire Mischevani lemon coat dress worn by Pippa Middleton, younger sister of the Princess of Wales, and Queen Rania of Jordan’s pastel yellow silk crepe tailored pencil dress with a bow collar by Tamara Ralph Couture.

Rose Hanbury, Marchioness of Cholmondeley, and Sarah Chatto, the daughter of Princess Margaret and Antony Armstrong-Jones, meanwhile, went for a shade between ivory and cream.

Hanbury wore a vintage dress by Ossie Clark from the Nineteen Seventies with a pair of black Aquazzura heels, the identical style Kate Middleton had worn a day earlier for public duties.

Chatto attended the ceremony in a v-neck pleated dress by Jasper Conran with a hat in the identical shade from Stephen Jones and accessories from Manolo Blahnik.

Holt also said she liked the chalky blue that Zara Tindall selected. She wore a coat dress by Laura Green with an identical fascinator, and accessorized her look with a Strathberry bag, Calleija diamond earrings, and diamond ribbon and tassel brooch from her mother Princess Anne.

Crown Princess Marie-Chantal also picked an analogous shade of baby blue for the coronation. She wore a custom dress by Mary Katrantzou, and carried the “In Search of Lost Time” clutch bag by Olympia Le-Tan.

Pastel tones were also popular among the many politicians who attended the event.

Olena Zelenska, first lady of Ukraine, wore an extended coat and an identical dress underneath in sage, a type of pastel green with grey and yellow undertones.

Sophie Trudeau, first lady of Canada, styled herself in a blush dress from high street brand Ted Baker, which is currently on sale for 157 kilos.

Finnegan Biden, granddaughter of President Joe Biden, attended the coronation along with her grandmother Jill Biden, first lady of the U.S. She opted for an extended, cream-yellow cape dress by Markarian. She accomplished her look with a yellow floral hairband and a small vanity case-style bag.

Britain’s home secretary Suella Braverman wore an ivory oversized fascinator in the form of a flower to match her dove grey outfit.

Julie Bishop, former Australian minister of foreign affairs, picked a fitted light beige dress with floral motifs from Zimmermann, an identical hat from Australian milliner Nerida Winter and a bag and shoes from Dior.
