LONDON — It took numerous savvy to compete with all of the regal ermine, purple satin and gold lace at Westminster Abbey, but a few of the biggest names in British design managed it, balancing tradition with style, and sending powerful messages with their designs for the coronation.

Sarah Burton of Alexander McQueen and Bruce Oldfield, particularly, had to construct outfits that would hold their very own under the ceremonial capes, robes and regalia. They’d to weave personal and British symbols into the clothing and create silhouettes easy enough to showcase heavy-duty accessories reminiscent of the crown jewels, and other royal heirlooms.

Most significantly, the designers had to make sure their creations made a press release on the day — and for posterity.

And there was no statement more powerful than the Princess of Wales’ leafy headpiece, crafted from silver bullion, crystals and silver threads. The elegant, sharp-edged band resembled the laurel crown of Julius Caesar, and was a fearsome statement-maker. It sent a “Don’t mess with me” style message from the recently-promoted royal, who’s more likely to be Britain’s queen someday.

The Princess of Wales could easily have worn a family tiara, but as a substitute selected to commission the headpiece, which was made by the British milliner Jess Collett in collaboration with McQueen’s Sarah Burton, her go-to designer and the girl who made her wedding dress in 2011.

The Prince and Princess of Wales have made clear they’re independent-minded, modern royals, in contact with their subjects and with the problems of the day. They need to be seen as compassionate changemakers, advocates for British charities and folks, and powerful parents to their three children.

The princess paired her leafy crown with an ivory silk crepe gown embellished with silver bullion and embroidery featuring rose, thistle, daffodil and shamrock motifs, symbolizing the countries that make up Great Britain: England, Scotland, Wales and Northern Ireland. Round her shoulders was the red and blue Royal Victorian Order Mantle.

All the ensemble nodded to Lee Alexander McQueen’s past designs, particularly the autumn 2008 show “The Girl Who Lived within the Tree.” Identical to the models on McQueen’s runway, the princess’ coronation outfit was red, white and blue, and topped with the glittery headpiece.

Burton also created a “mummy and me” matching outfit for Princess Charlotte, Kate Middleton’s only daughter.  

Burton topped Charlotte’s flowing, white dress with a capelet that featured the rose, thistle, daffodil and shamrock motifs just like those on her mother’s dress. Charlotte wore white mary jane shoes and a smaller version of the Princess of Wales’ headband, an extra nod to the royal family’s soft power.

The Princess of Wales picked Alexander McQueen once more for the coronation concert, which took place on the grounds of Windsor Castle on Sunday evening. She recycled a brilliant red McQueen trouser suit as she sat together with her family and watched Lionel Richie, Katy Perry and Take That perform live.

Oldfield — who designed quite a few dresses for Princess Diana through the years — had a fair larger challenge on his hands than Burton, and described the dress he designed for Queen Consort Camilla as “an important commission of my life.” Yet, like Burton, he also transmitted a message of soppy power.

Camilla not only needed to stand on the altar in front of 1000’s of guests and thousands and thousands of viewers; she also needed to don Queen Mary’s Crown with its 2,000 diamonds, including the famous Cullinan IV and V sparklers that Queen Elizabeth II loved a lot.

Oldfield’s gown was ivory, comprised of a peau de soie silk that was decorated with celebratory bunting done in antique gold and silver thread. The dress featured garlands of abstract wildflowers, daisy chains, forget-me-nots, celandine and scarlet pimpernel, symbols of the royal couple’s affection for nature, and for the British countryside.

As well as, on the underskirt and the cuffs of every sleeve were the flower emblems that represented the 4 nations of the U.K.

Oldfield told WWD that he’s been designing outfits for Camilla for greater than a decade, and that “the dress is a method and silhouette that Her Majesty likes very much. It’s sophisticated and appropriate for an occasion of grandeur reminiscent of this.”

He added that “the robe reflects a more fluid and modern representation of the king and the queen consort’s affection for nature and the British countryside. I believe it’s all the time a superb idea to look back at history — not simply to the late Queen Elizabeth II’s coronation gown, but to those before her as well, which I did.”

Jean Seaton, professor of media history on the University of Westminster in London, described the feminine royals’ outfits as refreshingly easy, elegant — and appropriate.

“They reflected a really modern Britain, and a hopeful Britain,” said Seaton. “There was no bling here. The ladies were dressed simply and beautifully, and you can tell the designers were enthusiastic about the roles the ladies were doing.”

Seaton noted that Camilla’s dress “wasn’t oppressively embroidered,” and thought the bunting added a “certain form of jollity” and lightness to the silhouette.

She added that the long, ivory dresses that Camilla’s two companions, her sister Annabel Elliot and The Marchioness of Lansdowne, wore were in tune with the mood of the event.

“These were very elegant dresses for mature women. The ladies didn’t appear like mutton dressed as lamb,” she said.

Designed by Fiona Clare, the British bridal and occasion wear designer, the 2 companions’ dresses were meant to enrich one another, and harmonize with Camilla’s gown. One had a standing collar with hand embroidered detail, while the opposite had silver edging.

One other British designer, Kim Jones, did double time on the day, designing the Dior men’s morning suit for Prince Harry, and the Fendi dress that Princess Eugenie wore.

Although his two royal clients could have been relegated to the third row at Westminster Abbey, Jones still had a serious job to do.

He had to assist Prince Harry look suitably regal in morning dress. The young royal, who renounced his duties to the British crown and whose relationship along with his father and brother Prince William have change into a worldwide soap opera, can not don military uniform for official events, although he can wear his medals and honors.

Jones dressed him in a custom-made black wool and mohair peak lapel vest and tailcoat, gray wool and mohair trousers, a white cotton shirt, and a gray silk tie.

Dior could have seemed a left-field pick for Harry, who isn’t exactly Mr. Fashion, but his wife Meghan Markle loves the brand, and probably made the introduction.

Jones had one other challenge in dressing Princess Eugenie, who’s heavily pregnant together with her second child. Together with his Fendi hat on, Jones designed a navy silk and satin mid-length dress with a plisse side-panel.

He also whipped up a navy and dark blue double-sided cashmere coat with an identical, embroidered obi belt. The pregnant princess also wore Fendi accessories, including a dark blue leather Fendi ISeeU Peekaboo bag with 3D leather roses; navy leather heels, and Swarovski embroidered navy silk and satin gloves.

Members of the royal family weren’t the one ones parading their finest, or sending messages with their clothing.

Some selected to make political statements, while others opted for a rainbow of refreshing pastels to mark the occasion.

First Lady Dr. Jill Biden and her granddaughter Finnegan Biden walked into the abbey wearing colours matching those of the Ukrainian flag.

Biden, who was attending on behalf of her husband, President Joe Biden, wore a Ralph Lauren periwinkle blue jacket with an asymmetric neckline; a knee-length pencil skirt, and matching gloves. She accessorized with a petit bow hat, a pair of cream heels, and a square clutch bag that matched her shoes. 

Finnegan Biden wore a protracted, cream yellow cape dress by Markarian. She accomplished her look with a yellow floral hairband and a small vanity case-style bag.

Carole Middleton, the mother of the Princess of Wales, and Pippa Middleton, the princess’ sister, also appeared together in blue and yellow.

Others who plumped for pastels included Queen Rania of Jordan, who wore a yellow silk crepe tailored pencil dress with a bow collar by Tamara Ralph Couture.

Sarah Chatto, the daughter of Princess Margaret and Antony Armstrong-Jones, wore a Jasper Conran belted dress in ivory and cream, and a hat by Stephen Jones.

Crown Princess Marie-Chantal of Greece wore a custom-made baby blue dress by Mary Katrantzou, and carried the “In Search of Lost Time” clutch bag by Olympia Le-Tan.

Katy Perry, who performed on the Windsor Castle coronation concert on Sunday night, opted for a pale lilac suit and hat by Vivienne Westwood, a designer who, despite her anti-Establishment status, actually admired the royal family, and King Charles III particularly.
