Meghan and Harry touched down in Ireland on Tuesday for a two-day visit - their first tour as husband and wife.
Serena is well established as one of her sport's all-time greats and winning the title for the third time in the last four years - she missed the 2017 tournament due to her pregnancy - would only enhance her standing.
To kick off day two in Dublin, Markle wore a chic taupe green dress by French designer Roland Mouret.
The Duke and Duchess of Sussex tied the nuptial knot on May 19, but rumours about Markle's pregnancy have been doing rounds even before their marriage.
Wearing a black trouser suit by Givenchy, a plain white tee and Sarah Flint heels, the duchess looked effortlessly cool and classy - nearly as if she was channeling her "Suits" character, Rachel Zane.
The Duke and Duchess of Sussex, who are now on their first overseas trip as a married couple, were attending a function at the British Ambassador's residence on Tuesday when she allegedly broke a golden rule of royalty: stay out of politics.
On way to Lahore, Nawaz Sharif urges Pakistanis to stand by him
The former prime minister and his daughter were in London, where Sharif's wife Begum Kulsoom is undergoing treatment for cancer. Maryam Nawaz tweeted a video message from her father after they stopped in Abu Dhabi before they travel on to Lahore .
It may seem odd for a father-in-law to do this, but, as Nicholl further explained, the royal family sees Meghan as "an ambassador" and want her to look and feel her best.
Considering Martin's next post was at a launch in Los Angeles, we can safely assume that the Duchess has been keeping up her DIY beauty skills while on tour in Ireland. She also carried a large Fendi bag in black leather. The boat neck dress featured an asymmetrical skirt and she accessorised her outfit with diamond drop earrings. Markle wore the ensemble with nude heels and a matching black fascinator for programming to honor the 100th anniversary of the Royal Air Force.
The duchess' looks were estimated to be worth $22,000 in total.
It could be that Markle has chose to relinquish that perk, having long favoured a more natural makeup look, even before she met Harry. "She's not really going to be available for working for the Royal Family on a full time basis until she's 40, I'm sure".
