Meghan Markle's Outfit At Prince Louis' Christening A Nod To Princess Diana

Meghan Markle paid tribute to Princess Diana again.

Prince Harry and Markle arrived at the Chapel Royal at St. James's Palace together for Prince Louis' christening. The Duchess of Cambridge donned an olive green outfit by Ralph Lauren for the event.

According to Joe Gamp, a journalist for Daily Express, Markle's wardrobe is a nod to Princess Diana. The late Princess of Wales was pictured wearing a number of olive green ensembles during her royal career.

In 1988, the People's Princess was photographed climbing into a tank during a visit to the Royal Hampshire regiment at Tidworth in a boiler suit. She was also seen chatting to a soldier in a camouflage gear as they went about their military exercises.

Green is among Princess Diana's favorite color. She was often seen wearing an ensemble in this shade when she undertook her royal duties with her ex-husband, Prince Charles.

According to a fashion expert, Markle's fashion convention is reminiscent of Princess Diana. "We can all look to Meghan to flex the rules a little and push boundaries in the same way that Diana did," Vanessa Collen, founder of luxury independent fashion boutique, Collen & Clare, told Express.

Markle's fashion is also often compared to her sister-in-law, Kate Middleton. A number of stylists have noticed that her fashion has become similar to the Duchess of Cambridge. In fact, one says that she's morphing into Middleton after becoming an official royal.

"Meghan's style certainly bears more resemblance to Kate's since she became Duchess," Anna Mewes, a personal stylist, told Express. "Her overall look has become more polished and her hair at recent Royal engagements has been styled in glossy curls and understated up-dos which are almost identical to Kate's."

Caroline Castigliano also observed the same thing. According to the designer, the former "Suits" actress is taking a much bigger role and has been dressing like the royal mom of three.

"The royal family is a firm and the protocol is huge," Castigliano 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," the designer added.
