Princess Diana's brother wore a purple tie to emphasize wife's elegant gown

Earl Spencer and his wife Karen looked flawless as they arrived at Windsor Castle for the wedding of Prince Harry and Meghan Markle on May 20, combining both outfits cleverly.

Spencer, who’s Diana’s younger brother wore a purple tie that matched his wife’s stylish violet outfit and striking hat. He is one of the most prominent members of the Spencer clan, many of whom have kept to themselves since Diana’s death.

As Vanity Fair reported, Harry wanted to make sure that his late mother was not going to be forgotten on the day of his wedding, and he invited all of his relatives on his mother side to the celebration.

Shortly after Spencer’s arrival at the wedding site, his sisters Lady Jane Fellowes and Lady Sarah McCorquodale followed, and as was announced previously, Lady Jane, the oldest of the siblings, had an important role in the ceremony.

During the religious service at St. George’s Chapel, Lady Jane read a bible passage from the Song of Solomon in a very emotional moment, according to Zimbio.

Although Prince Harry was just 12-years-old when Diana tragically passed away in 1997, he always remained close to his mother’s side of the family, and he made sure to honor his mother with the presence of her relatives.

Early on the relationship between Harry and Markle, the 33-year-old prince introduced his girlfriend –at that moment- to his uncle and aunts on the Spencer side, as well as other people close to his mother, such as friend Julia Samuel.

Markle told this exclusively to CNN on the couple’s official engagement interview in November 2017.

‘I think in being able to meet his aunts and - and also like Julia and different people who were so important to his mum, I'm able to, in some way, know a part of her through them and of course through him. And it's - it's incredibly special,’ she said.
