Regal fashion: Looking back at who wore what for King Charles' coronation

Malaysia's King and Queen, Yang di-Pertuan Agong Al-Sultan Abdullah Ri’ayatuddin Al-Mustafa Billah Shah and Raja Permaisuri Agong Tunku Hajah Azizah Aminah Maimunah Iskandariah attend the coronation ceremony of King Charles.

What does one wear to a coronation? That was probably the question on a lot of people's mind when it comes to the crowning of King Charles on Saturday (May 6).

For senior royals like Queen Camilla and Kate, the Princess of Wales, the theme was pale, subdued dresses to let their regal robes and glittering jewellery do the talking.

Camilla, who was crowned alongside King Charles III at Westminster Abbey on Saturday, wore an embroidered silk gown in ivory, silver and gold tones with a short train by Bruce Oldfield – a British designer favored by the royal family - with matching shoes.

Kate wore an ivory silk crepe dress by British fashion house Alexander McQueen under her cobalt blue and red Royal Victorian Order mantle, or robe. She didn’t wear a tiara, instead opting for a large silver and crystal headpiece designed by milliner Jess Collett in collaboration with McQueen.

She also sported pearl and diamond earrings belonging to William’s late mother, Princess Diana.

Her eight-year-old daughter, Princess Charlotte, wore a similar headpiece and ivory McQueen dress with cape, embroidered with rose, thistle, daffodil and shamrock motifs to represent the four countries of the United Kingdom.

Many of the guests opted for eye-catching pastel outfits that provided cheerful pops of colour in the wet grey weather.

US first lady Jill Biden wore a cornflower blue skirt suit by Ralph Lauren, with a matching hairpiece and gloves. She appeared with her granddaughter Finnegan Biden, who wore a yellow dress with matching cape by New York label Markarian.

Pink was a particularly popular choice for many. France's Brigitte Macron chose a pale pink short dress with matching coat, by designer Nicolas Ghesquiere for Louis Vuitton. Spain’s Queen Letizia also opted for pink, sporting a skirt suit with peplum frills, matching heels, and a large stylish hat.

Pop star Katy Perry, who is due to perform at a coronation concert Sunday, wore a Vivienne Westwood jacket with matching tailored skirt. She styled the tailored look with a headpiece featuring a crinoline base with a layer of tulle and merry widow veiling, adorned with a ribbon bow.
