As one might expect, the stakes are high when it comes to mapping out a royal wedding guest outfit that would garner even Queen Elizabeth II's stamp of approval. Naturally, any old dress from the back of your closet simply won't do, and A-listers have pulled out all the fashion stops over the years. From elaborate fascinators to bold (knee-length) dresses and overcoats, guest apparel certainly proves that weddings of royal proportions aren't your standard nuptials (as if we didn't already know that).
Ahead, we're revisiting guest looks from royal weddings past. See the best-dressed list from around the world—and maybe find some wedding guest outfit inspiration of your own—featuring appearances from Victoria Beckham to Nancy Reagan.
Princess Beatrice kept her outfit simple for Prince Jean-Christophe Napoleon Bonaparte, a descendent of Napoleon Bonaparte I, and Countess Olympia von und zu Arco-Zinneberg's French royal wedding in October 2019. She paired a floral dress with a pale blue trench coat and a pink wide-brimmed hat. Arguably, the best accessory was her newly-minted fiancé Edoardo Mapelli Mozzi on her arm.
While this won't be the only time Pippa Middleton makes the best dressed list, we love this dress from Kate Spade, which she wore to Lady Gabriella Windsor's wedding in May 2019. The light blue floral frock was perfect for springtime nuptials, and the velvet headband added a refreshing take on the royal wedding accessory in a sea of fascinators and hats.
Just a few months after her own "I do's," Meghan Markle attended a ceremony at St. George's Chapel for Princess Eugenie and Jack Brooksbank's wedding. The Duchess arrived in style wearing a navy blue ensemble designed by Givenchy, her own royal wedding dress designer.
Kate Middleton also attended Princess Eugenie's royal wedding wearing her royal wedding dress designer, Alexander McQueen. The Duchess chose a pink long-sleeve dress and matching fascinator for the autumnal occasion.
Model-turned-actress Cara Delevingne rocked a fitted tuxedo and top hat to Princess Eugenie's October 2018 nuptials. For a royal wedding, the look was edgy, unexpected perfection.
Pippa Middleton (...Again)
Monochrome appeared to be a popular trend among A-list guests at Princess Eugenie's wedding. A then-pregnant Pippa Middleton flaunted her growing baby bump in an emerald green outfit.
Prince Carl and Princess Sofia of Sweden
While attending the wedding of Prince Konstantin and Princess Deniz of Bavaria (whose wedding style closely resembled that of Meghan Markle's), the Swedish royals looked like a fairytale come-to-life. We're getting major Cinderella vibes from Princess Sofia's baby blue gown, and her better half had the whole "Prince Charming" thing down in a black tux.
Kicking off Prince Harry and Meghan Markle's royal wedding, Amal Clooney arrived on the scene dressed like a literal ray of sunshine, sporting a vibrant Stella McCartney creation. Naturally, her husband George looked dapper as well.
Also styled in custom Stella McCartney, Oprah Winfrey turned heads at Harry and Meghan's wedding in a light pink number—that came together literally hours before the wedding. After deciding that her original beige dress appeared too close to white, the designer's team stayed up all night to recreate her gown in a more wedding-friendly hue.
It wouldn't be an Elton John ensemble without a pair of funky shades. The singer performed at the Duke and Duchess of Sussex's lunchtime wedding reception in a gray suit.
Victoria and David Beckham
This isn't the only time you'll see the Beckhams on this list. Victoria donned one of her own creations to watch Harry and Meghan say "I do," which she paired with bright pumps. David, on the other hand, rocked a gray Dior Homme custom-made morning suit.
Princess Caroline of Hanover
Princess Caroline, the daughter of actress Grace Kelly and Prince Rainier III of Monaco, almost outshone the bride at her son Pierre Casiraghi's wedding to Beatrice Borromeo in 2015. Contrasting colors and shimmery details make Caroline's gown an enviable mother-of-the-groom look.
Diane von Furstenberg
The fashion designer sported a wow-worthy dress to Pierre Casiraghi's Italian nuptials. Perfect for the August ceremony, she sported a floral yellow ensemble, while putting her best foot forward in a pair of gold kicks.
Prior to their own royal nuptials, Beatrice Borromeo and Pierre Casiraghi attended Prince Felix Of Luxembourg and Claire Lademacher's wedding in 2013. Borromeo looked pretty in pink with a light, tailored pantsuit. And, can we talk about that one-of-a-kind headpiece? Upcoming royal wedding guests, take note.
Victoria and David Beckham (...Again)
Posh took her nickname to heart, wearing a fashion-forward look for Prince William and Kate Middleton's wedding in 2011. Sky-high heels topped off the former Spice Girl's all-navy look, which included a high-low dress with a royal wedding-appropriate hemline.
This London TV personality and socialite put the "royal" in royal blue. She opted for a monochromatic dress, gloves, heels, and geometric fascinator at Will and Kate's wedding.
Queen Elizabeth II
The royal matriarch, who's known for her colorful wardrobe, opted for a cheerful, yellow outfit. The Queen was all smiles at her grandson Prince William's wedding, wearing a coat dress and matching hat. She also wore a brooch from her collection, the True Lover's Knot design.
Princess Clotilde Courau
Meanwhile, in Monaco, Prince Albert II and Charlene Wittstock also tied the knot in 2011. Guest Princess Clotilde Courau, married to Prince Emanuele Filiberto of Savoy, stunned in a head-turning, ruffled red dress with black accessories.
Fashion legend Karl Lagerfeld also attended Prince Albert II and Princess Charlene's 2011 nuptials and unsurprisingly took the royal wedding dress code to trendy new heights. The creative director behind Chanel opted for studded gloves and a brooch to personalize his formal guest attire.
Giorgio and Roberta Armani
Giorgio Armani, another fashion powerhouse, went to the Monaco royal wedding with his niece Roberta. The designer looked dapper with a silver tie and vest, while Roberta stole the show in an ultra-modern brown dress.
This supermodel made an entrance at Prince Albert II's ceremony with a navy peplum look, featuring a fitted skirt and an embellished black train.
Kate Middleton (...Again)
Just a few months after her own wedding, Kate and Prince William attended the wedding of Mike and Zara Tindall, the Queen's eldest granddaughter. To commemorate one of her first royal outings, the Duchess looked the dignified part in a cream and yellow patterned coat with a chic fascinator.
At the same wedding, British actress Katherine Kelly rocked a colorful, wide-brimmed hat and a more demure cream, one-shoulder gown.
Princess Marie-Chantal Miller
If this royal bride's wedding dress has taught us anything, it's that this princess knows a thing or two about impeccable style. For Prince Nikolaos and Tatiana Blatnik's 2010 nuptials, Princess Marie-Chantal turned to a floor-length, trumpet-style pink gown. An embroidered shawl with floral appliqués topped off the Grecian wedding look.
Queen Rania of Jordan
Channeling the ultimate Carolina Herrera vibe, Queen Rania wowed in a white blouse tucked into a lavender skirt as a guest at Crown Prince Felipe Of Spain and Letizia Ortiz Rocasolano's 2004 wedding.
The People's Princess was known for her iconic sense of style, which is apparent here in 1988 when she attended the wedding of Julia Rawlinson and James Ogilvy, son of Princess Alexandra of Kent. Diana's look reads classic and effortless, as she sports a white dress and hat, gray coat, and pearl accessories.
The Queen Mother
The Queen Mother donned a light blue look, complete with a fluffy headpiece (it was the '80s, after all) to the wedding of Princess Diana and Prince Charles.
Frances Shand Kydd
Princess Diana's mother, seen here with Prince Philip on her daughter's wedding day, also channeled blue hues at the 1981 royal wedding. The mother-of-the-bride accessorized with a tasteful hat and pearl necklace.
Former first lady Nancy Reagan opted for a timeless ensemble to Prince Charles and Princess Diana's ceremony. She sported a simple dress and hat, paired with gloves, a cardigan, neck scarf, and subtle accessories.
Donning a sharp navy blue suit and matching tie, actor Idris Elba arrived at Prince Harry and Meghan Markle’s 2018 nuptials in style. Since the royal couple asked The Suicide Squad star to DJ their reception, he wanted to dress the part. Elba coordinated perfectly with his then fiancée, Sabrina Dhowre, who was wearing Gucci.
Actress Priyanka Chopra looked effortlessly elegant at Prince Harry and Meghan Markle’s wedding in a lavender custom suit by Vivienne Westwood. As a close friend of Meghan’s, the Quantico star wanted her outfit made specially for the occasion, so she had the suit handcrafted in Westwood’s London atelier. Chopra topped off her look with a Philip Treacy hat in the same pastel hue.
Lady Kitty Spencer
A strong sense of fashion must run in the family because Princess Diana’s niece, Lady Kitty Spencer, looked ravishing at Prince Harry and Meghan Markle’s nuptials. The fashion model sported an emerald green dress with a square neckline and a lush floral illustration from Dolce & Gabbana. She pulled her look together with orange heels, an orange clutch, and an emerald green fascinator.
Tennis superstar Serena Williams traded her tennis whites for a pretty pink ensemble at Prince Harry and Meghan Markle’s wedding. Williams rocked a pink Versace dress with an asymmetrical neckline, long sleeves, and a cinched waist. Her statement fascinator and Bulgari jewelry (along with husband Alexis Ohanian as arm candy) completed her attire.
