Now in a big move since joining the Royal Family, she has released a cook book in aide of the Grenfell Tower tragedy.
Meghan Markle wore a £1,483 outfit to launch the Grenfell cookbook with mum Doria & Prince Harry.
The most striking element of Meghan’s look was her blue coat, which was from Canadian brand SMYTHE, and costs an eye-watering £1,186.
Judi James told Express.co.uk: “Meghan is a very smart speaker because her acting experience allows her to combine four subtle but powerful body language techniques to produce a natural-looking style of delivery that is also pitched perfectly for her audience.”
Meghan Markle’s body language tricks revealed
The ‘Upturned V’ gap
Judi said: “Firstly (Meghan) uses what is called the ‘Upturned V’ gap under her armpits.”
According to Judi this armpit gap can display confidence or a lack of it if the arms are held tight to the body.
Judi said of Meghan: “This gap size is ideal, with the elbows held away from the waist, and is a gesture used effectively by Michelle Obama as well.
“It also has an interpersonal effect, making a speaker feel more confident as well as looking it.”
Meghan’s has a very powerful skill when it comes to eye contact, according to Judi.
She said: “Meghan uses an all-embracing scope of eye contact.
“She connects with the entire audience here by scanning round with her eyes.”
Scooping movement with splayed fingers
Judi said: “Her emphatic hand gesture is a scooping movement with splayed fingers.
“This projects passion and enthusiasm for her cause.”
Judi said: “Then Meghan brings her hands back into a clasp in between gestures, pulling the hands over and back slightly in a signal of self-effacing modesty.”
Judi James also analysed Prince Charles’ body language during an interview in which he asserted he tried to be faithful to Princess Diana.
In a resurfaced clip from Prince Charles: His Children, the Paparazzi & Marriage to Diana, Prince Charles addressed the divorce.
Charles was grilled by an interviewer on the break down of his marriage and whether he was unfaithful to his wife.
Who is Meghan Markle? Quick profile
Meghan Markle was born Rachel Meghan Markle, on August 4, 1981 to parents Doria Ragland and father Thomas Markle.
Her father was previously married to Roslyn Loveless and Meghan has two elder half sibling – sister Samantha Markle and brother Thomas Markle Junior.
Meghan’s first television appearance in the USA was in an episode of the medical drama General Hospital in 2002.
She later moved on to roles in CSI, Without a Trace and Castle along with bit parts in Hollywood films including Get Him to the Greek, Remember Me and Horrible Bosses.
Meghan was also a “briefcase girl” on Deal or No Deal – but her most famous role was as Rachel Zane in legal drama Suits, which launched in 2011.
She was written out in the finale of the seventh series when her character got married, which aired in April 2018 – just before she got married herself.
Charity and humanitarian work
Meghan Markle’s career in television has gone hand-in-hand with her support for causes close to her heart.
She wrote about the stigma around menstrual health in an article for Time magazine and was a Global Ambassador for World Vision Canada – with whom she travelled to Rwanda for the charity’s Clean Water Campaign.
And her commitment to gender equality has seen her work with the United Nations – receiving a standing ovation in 2015 for her speech to mark International Women’s Day.
In September 2011, she wed film producer Trevor Engelson, who she began dating in 2004.
But the pair divorced two years later in August 2013, citing irreconcilable difference.
She was in a relationship with celebrity chef Cory Vitiello for almost two years, before they broke it off in 2016 but the two remain good friends.
And in June 2016, she met Prince Harry on a blind date set up by a mutual friend.
Their relationship began in October that year and just over one year later, on November 27, 2017, the pair announced their engagement.
They married on May 19, 2018 at St George’s Chapel in Windsor Castle.
Some have claimed Meghan Markle is the first mixed-race member of the Royal Family.
Historians are still arguing about Queen Charlotte, the wife of King George III.
But Meghan will be the first royal to openly embrace a mixed-race heritage.
She has written about the difficulties of being a biracial actress in Hollywood as she claims she is not black enough for some roles and not white enough for others.
