The Royals turned out en masse for yesterday's Easter Sunday service at St. George's Chapel, Windsor – the church where Prince Harry and Meghan Markle are set to marry this May.
Whilst the Prince and his bride-to-be were not in attendance, The Queen led proceedings alongside a number of her grandchildren, including Princess Beatrice and Princess Eugenie, Lady Louisa Windsor and James, Viscount Severn.
Also in attendance were Prince William and the Duchess of Cambridge, whose arrival demonstrated, interestingly, a departure from the norm...
The Duchess, who is set to give birth to her third child in a number of weeks, arrived with her husband by car. Nothing unusual in that, you might think, only tradition dictates that members of the Royal family walk down the hill from Windsor Castle to the Chapel for the Easter service.
Not only that, but the couple broke with Royal protocol by arriving after The Queen; the 'rules' state that The Queen should arrive last to any event and leave first.
Whilst it's most likely this occurred on account of Catherine's pregnancy – plus, let's not forget, she was also in heels (nude Gianvito Rossi pumps, in case you're wondering) – it does show that in some aspects of Royal life, there is an increasing trend towards the relaxing of past traditions (we need only look at Meghan Markle's inclusion at the Royal Christmas last year to see quite how time's are a-changing...).
Indeed, one of the only other instances where this rule was 'broken,' occurred at the state funeral of Sir Winston Churchill at St. Paul's Cathedral in 1952. To show respect to her dearly-cherished former Prime Minister, The Queen chose to arrive before his coffin and family, and left after them too.
But back to this Easter Day, Catherine paired her pumps with a brown Catherine Walker coat, which she last wore in 2015 to the St. Patrick's Day celebrations just before giving birth to Princess Charlotte. We might assume, therefore, that it's clearly very comfortable maternity wear. She completed her outfit with a brown Lock & Co hat and earrings by Balenciaga.
By contrast, The Queen looked most colourful dressed in a fuschia pink jacket and hat; her granddaughter pregnant Zara Phillips wore blue and another of her granddaughters, Princess Eugenie, set social media abuzz by wearing a vibrant Oscar de la Renta paint-splattered buttoned dress (it's now sold out from Selfridges, but was on sale for £2,615).
In all, it was a colourful display by the Royals, befitting the arrival of the new season of spring. If it ever stops raining, that is...
