Meghan Markle and Prince Harry Attend Royal Christening of Prince Louis

The Duke and Duchess of Sussex, Meghan Markle and Prince Harry, were among the guests at the royal christening of their nephew, Prince Louis, on Monday.

The ceremony took place at the Chapel Royal at St James's Palace in London, where Meghan was baptised earlier this year.

The royal couple arrived alongside Prince William and Kate Middleton.

Meghan wore an olive green Ralph Lauren dress with a boatneck style, which is one of her signature looks.

She paired the dress with a matching headpiece by Stephen Jones, olive green gloves, and a clutch.

The couple also reunited with the Archbishop of Canterbury, Justin Welby, who officiated their royal wedding on May 19.

Meghan shared a friendly laugh with Welby before entering the chapel.

Since their engagement last November, Meghan has celebrated several important occasions with the royal family.

She joined Queen Elizabeth for her annual Christmas luncheon and holiday festivities in Sandringham alongside Prince William, Kate, and their children, Prince George and Princess Charlotte.

In June, Meghan made her big balcony debut at Buckingham Palace during Trooping the Colour.

During their wedding day, Meghan and Harry included George and Charlotte in their wedding party, giving her the chance to get to know her niece and nephew even better.

Since the newlyweds are neighbours with Prince William and Kate at Kensington Palace, they have had even more opportunities to spend time with the children.

The couple has a busy week ahead.

On Tuesday, they are heading to Dublin for their next big outing.

They will spend two days in the Irish capital, which will include a trip to Guinness Storehouse.

In the fall, Harry and Meghan will also head to Australia, Fiji, the Kingdom of Tonga, and New Zealand for their first royal tour as a married couple.
