Meghan Markle and Kate Middleton share the some good traits and are likely to support each other, according to one expert.

A comparative analysis of their handwriting recently revealed that the Duchess of Sussex and the Duchess of Cambridge are both loyal people. But there are some differences when it comes to who they trust. "[They] are both genuinely loyal to the ones they feel closest to," Jamie Mason Cohen said. "[Middleton] is extremely loyal to her family and close friends. She has had some of the same friends for many years."

"She displays a high degree of loyalty in her relationships," Cohen added about Middleton. "Her family and friends confide in her because she is a warm, empathetic listener whose sensitivity helps her relate and understand others' pain."

Cohen described Middleton as "loyal and trusting." On the other hand, Markle has the same loyal quality, but has trust issues.

"Meghan holds loyalty to a small group of trusted people," Cohen continued. "She keeps most other people at arms-length behind a polite yet distant smile as it’s hard for her to trust anyone and let people in."

In related news, Middleton is reportedly helping Markle with her fashion choices, which explains why the new royal's clothing is becoming similar to that of the royal mom of three. According to a designer, Markle has changed since she officially joined the Firm and has been dressing like Middleton.

"The royal family is a firm and the protocol is huge," Caroline Castigliano, a British designer, said. "We're seeing everything about Meghan change. It's very difficult when you're 36 to do this. It's far easier when you're in your early 20s and they can mould and adapt you."

"It's a much bigger job for Meghan. It must be unbelievably difficult that Meghan was a working woman and had her own style. At the moment, she's really dressing like Kate," she added.

A week ago, Markle joined Queen Elizabeth II and Prince Harry at the Queen's Young Leaders Awards ceremony where many noticed that her makeup and hairstyle were similar to Middleton's. The new duchess opted for very shimmery cheeks and Middleton's signature curls.

Although Markle looked great with Middleton's hairstyle, a designer advised that she needs to leave the curls to the Duchess of Cambridge and find her own signature hairstyle.

"In my opinion, although this hairstyle [curls] is always going to be on trend, I think it should left to Kate to pull this off too, Meghan needs her own stamp," celebrity hairdresser James Johnson said.
