Good things come in threes, including Meghan Markle's chic outfits. The Duchess of Sussex stepped out in her third stunning look of the day while arriving to a garden party at the British Ambassador's residence in Dublin, Ireland. The ensemble consisted of a sleeveless little black dress by Emilia Wickstead with an A-line silhouette, square neckline, and belt. She let her hair down into sleek, loose curls separated by a deep side part.

A pleasure to meet Prince Harry & the Duchess of Sussex at the British Ambassador's Residence this evening.

The occasion, which the Duchess is attending with Prince Harry, is part of the couple's joint tour of Ireland, their first working trip abroad as a married couple. After touching down in Dublin this afternoon, the pair had a private meeting with the Irish Prime Minister Leo Varadkar.

Next on their schedule is a garden party at Glencairn, the residence of Robin Barnett, Britain’s Ambassador to Ireland, Mirror reports. Prince Harry reportedly gave a speech, according to royal correspondents on Twitter.

Prince Harry gave a warm speech in Dublin tonight: Standing here with you on this beautiful evening, it is easy to see why Ireland has such a special place in the hearts of my family and indeed,
all those who come here.

Harry just gave a speech at the summer party: “It is easy to see why Ireland has such a special place in the hearts of my family... We’re so pleased to be here, for our first official international visit together as a married couple, and we hope it will be the first of many!” pic.twitter.com/YrsC6g26A0

Markle has shown serious sartorial range with just her royal engagements today. She started off this morning in a bespoke Dior look—another little black dress—for a service celebrating the Royal Air Force's 100th anniversary. She went the ladylike route in her boatneck dress, black fascinator, and pumps.

Next, she opted for emerald while landing in Dublin, as a sweet tribute to Ireland. The sophisticated, business-friendly look included a deep green top, Givenchy pencil skirt, and tan Strathberry tote bag.

Meghan and Harry's official trip to Ireland only lasts for two days, but if today taught us anything, it's that we should expect to see a lot more royal looks from the Duchess during their brief stay.
