Meghan Markle has to thank Kate Middleton for the successful launch of her charity fashion line, according to a royal expert.

On Thursday, the Duchess of Sussex has officially returned to her royal duties. Markle arrived at the launching of her capsule collection for Smart Works. She arrived in a smart white shirt and black trousers.

According to Phil Dampier and Graeme Culliford, Markle owes her success to her sister-in-law. “Many think she has sister-in-law Kate to thank — as she looks to bury their differences and learn from the woman best placed to help her,” they wrote on The Sun.

An insider revealed that Markle has already accepted that she had lost her way and lost her mojo. Prince Harry’s wife realized that she needs to take radical action to get the public back on board and fall for her again just like they did when she was still dating the Duke of Sussex.

“Kate is a huge inspiration, as she has provided a princess masterclass since she married William, and Meghan realises she has a lot to learn from her,” a source said.

“Kate has been constantly graceful and elegant — flawless, actually — and has an intuition for how ordinary British people think and feel about things, which Meghan has struggled to grasp. Meghan knows her reputation has taken a battering and she has made big mistakes, but she is convinced she can turn it round.”

The insider added that from now on the people would see a different Duchess of Sussex - one that is more humble and considerate. Someone who is basically like Middleton.

The people were expecting Middleton and Markle to be best friends because they are close in age and Markle’s husband, Prince Harry, was very close to the Duke and Duchess of Cambridge. However, the two duchesses defied the people’s expectations by not forging a close friendship.

According to Ashley Pearson, this isn’t surprising as Middleton and Markle are very different. Middleton follows the royal protocol while Markle challenges it. She added that the two women are fully grown-up and they have their own style and opinion when it comes to the royal protocol.
