The royal family are well known for using their clothing to portray a message, and that doesn't change when they are mourning a loss.
In fact, royals follow a number of traditions out of respect for those that have passed - famously, Queen Victoria spent 40 years wearing black in tribute to her late husband Prince Albert as an outward sign of her grief.
Mourning veils are a core aspect of royal funeral dress
Following the death of her husband Prince Philip on April 9, the late Queen expressed her wish that the royal family would observe two weeks of royal mourning, with a senior palace official stating that "mourning bands will be worn where appropriate". This was also the case for her own funeral arrangements on Monday 19 September.
Traditional black, mourning veils and military dress are all appropriate options for funeral dress amongst the royal family. Here, we look back at the poignant choices over the years...

Upon her uncle the Duke of Windsor's passing in 1972, the Queen chose to wear a hat and coat to his funeral. His wife Wallis Simpson wore a black veil and matching coat.
