Meghan Markle is bringing back a no-fuss hairstyle that anyone can replicate

It doesn't necessarily take a hairstylist to get Meghan Markle's latest look.

On Friday, the 36-year-old actress and her fiance, Prince Harry, made a surprise appearance in Belfast, Northern Ireland, and once again all eyes were on the bride to be.

Meghan stepped out in a teal, fitted Greta Constantine skirt, brown pumps and an off-white sweater, but perhaps what was most astounding about her style is how she managed to make a messy side bun look so flawless.

This isn't the first time the Suits star has pulled off this casual hairstyle. In January, she also sported a low messy bun when she and Harry visited Cardiff Castle in Cardiff, Wales.

Royal expert Katie Nicholl tells ET that while Meghan's hair isn't always done up, she definitely seems to be getting some help with her look.

"If you compare Meghan at the Invictus Games [in September] -- when she turned up in ripped jeans and flat pumps with slightly messy hair -- to that very polished, poised performance at the Commonwealth Service, it looks very much to me as if there is someone behind the scenes helping her dress more royally," Nicholl noted. "She certainly seems to be opting for more conservative designers and really stepping up to the plate in terms of royal dressing and presenting herself as a future princess."

Meghan has looked to her future sister-in-law, Kate Middleton, for "advice on royal fashion and go-to designers," a source told ET earlier this month.

Another source further noted that the royal family is "embracing" Meghan ahead of her wedding to Harry on May 19.

"Both Kate and Camilla [Duchess of Cornwall] have been doing what they can to make sure Meghan knows she’s loved and supported as she navigates her life as a future royal," the source said, explaining that becoming a royal member can be isolating. "She’s been embraced by the royal family. She’s also been exploring various charitable avenues she'd like to pursue after she gets married."
