And while the attendees’ choices of outfit were appropriately understated, hats, brooches and nods to national dress added character to the otherwise sombre attire.
Formal headpieces came in all shapes and sizes, from wide-brimmed hats to diminutive fascinators with dark veils.
More elaborate designs were seen on Carole Middleton, the mother of Catherine, Princess of Wales, and Britain’s Leader of the House of Commons Penny Mordaunt, whose hat featured an arrangement of dark feathers.
French President Emmanuel Macron’s wife, Brigitte, opted for pillbox-style hat with small black veil detailing at the front; Jill Biden’s was more minimal, with a thin headband-like design culminating in a delicate bow.
Indeed, no royal was too young to abide by tradition, with seven-year-old Princess Charlotte, now third in line to the throne also pictured in a dark hat.
For others from the Queen’s immediate family, outfits, sashes and medals were dictated by military rank.
No longer a working royal, Prince Andrew instead wore a simple morning suit, though it was nonetheless embellished with various medals and decorations.
Making statements is a delicate task, but brooches, pins and sashes carried subtle significance.
Camilla, the Queen Consort, went further back in history with the heart-shaped Hessian Diamond Jubilee Brooch, a sapphire-encrusted jewel once owned by Queen Victoria, the late Queen Elizabeth’s great-great grandmother.
New Zealand’s Prime Minister Jacinda Ardern, who often uses high-profile moments to nod to her country’s indigenous traditions, wore a feathered Māori cloak.
Speaking ahead of the funeral, she told one of her country’s domestic broadcasters, 1News, that the garment gave her “some way to bring a piece of New Zealand here with me.”
Other overseas dignitaries turned to their country’s national dress, too.
The Crown Prince of Bahrain arrived in a thobe and ghitraa, the ankle-length robe and headdress widely worn by men in the Gulf nation.
Nigeria’s vice president Yemi Osinbajo also arrived in traditional dress, while Pakistan’s Prime Minister Shehbaz Sharif wore a black sherwani.
