13 of the best outfits royals have worn for Easter services

In 2018, Queen Elizabeth attended Easter services at St George's Chapel in Windsor wearing a bright-purple coat, floral dress, and matching hat adorned with purple and orange flowers.

Royals wear hats to formal occasions like Easter and Christmas Day services per royal protocol, but the monarch always found ways to make her outfits stand out.

The royal was easy to spot in a robin's-egg-blue coat and wide-brimmed hat accented by fuchsia flowers.

There was actually a logical reason why the Queen often chose bright colors for her public appearances. 

According to her daughter-in-law Sophie, the Countess of Wessex, who is married to her youngest son Edward, the Queen often opted for colorful looks during her reign to make her easier to see.

"She needs to stand out for people to be able to say 'I saw the Queen,'" she said in the Smithsonian Channel documentary "The Queen at 90." "Don't forget that when she turns up somewhere, the crowds are two, three, four, 10, 15 deep, and someone wants to be able to say they saw a bit of the Queen's hat as she went past."

In 2017, the Princess of Wales attended services at St George's Chapel in a pale-pink coat and matching pumps. She accented her chic look with a pillbox hat, another favorite accessory among royal women.

Her entire spring look, from her hat down to her heels, was color coordinated. 

The royal accessorized her sky-blue coatdress with a slightly darker-colored hat and matching shoes. Her clutch purse, however, was exactly the same color as her dress.

Princess Diana attended Easter services with her sons, Prince Harry and Prince William, in 1991, standing out from the pack in a festive pink gingham suit and hat with netting across her face.

Her pale-yellow dress, which perfectly matched her coat, had black trim. She finished off the look with a black hat also trimmed in yellow, black tights, and simple black pumps.

The look was demure, but a departure from the pastel-colored styles royals typically choose to wear for the Easter holiday.

In 2019, Prince Harry attended Easter Sunday services without his wife, Meghan Markle, at St George's Chapel in Windsor. He wore a classic navy suit accented with a Tiffany-blue tie.

The royal, who is known for her bold yet affordable style, wore cream-colored slacks and a pastel-orange blazer for Easter in 2009.

The wife of King Felipe VI, who ascended to the throne in 2014, accessorized her look with a leather clutch and navy-blue heels.
