The Duchess is clearly a big fan of the black suit - she actually wore a black tuxedo style two-piece at the Endeavour Fund Awards in London in February which she paired with a white shirt.
She wore her tresses in an elegant side bun, which celebrity hair stylist Jason Collier says is a "sleeker and more elegant" take on what is fast becoming her signature look. And while there are many benefits that come with being a member of the royal family, there are some things that Meghan has had to give up.
Wickstead, who is already a firm design favourite of Kate Middleton, made headlines in May this year after openly criticising Markle's Givenchy wedding gown and accusing the designer, Clare Waight Keller, of copying her.
Harry and Meghan arrived at Áras an Uachtaráin at around 9.30am on Wednesday.
Meghan Markle seemingly broke royal protocol when she and Prince Harry were on their first overseas trip as a married couple.

Two other Americans were wounded in the attack. "We're counting on all the actors in the region to be supportive". Insider attacks are commonly referred to as "green on blue" attacks.
Markle revisited Givenchy with a high-waisted knit pencil skirt in a midi length, adorned with vintage-inspired buttons at the pockets.
Over the course of the trip, Their Royal Highnesses will meet the people of Dublin and will visit organisations which are central to Irish life.
The royal couple also visited the headquarters of the Gaelic Athletic Association, the scene of the Bloody Sunday massacre committed by British troops against civilians in 1920.
Meetings with The President of Ireland, Michael Higgins, and with The Taoiseach, Leo Varadkar, are both planned.
Markle's third outfit choice was the Emilia Wickstead dress which she wore with simple black heels to the garden party reception at the British Ambassador's residence in Dublin.
