British royal family member Princess Beatrice elevated her Ralph Lauren shirtdress in a pair of black strappy Zara heels while volunteering at the BGC Group Charity Day on Thursday.

Attending the event on behalf of CFRF, the Commercial Fisheries Research Foundation, Princess Beatrice wore the double-faced Georgette shirtdress in black by Ralph Lauren. The midi frock featured a fit-and-flare silhouette, emphasizing the waist with a flowy skirt and fitted bodice.

The bodice of the garment also included a sharp collar, with rolled sleeves and button detailing at the cuffs. Small white buttons formed down the front placket of the dress, giving the look a casual appearance with hints of versatility and uniform appeal.

When it came to her footwear, Princess Beatrice wore a pair of buckle high heels from Zara. While members of the British royal family tend to favor designers and fashion labels based in London and the United Kingdom, it’s not completely uncommon for the royals to look to designers across the pond for their respective wardrobes.

Kate Middleton has also endorsed Ralph Lauren’s designs. On Sept. 4, the Princess of Wales stepped out for a public engagement alongside Prince William at the National History Museum wearing a muted green blazer by the American designer, which complemented the British royal’s newly blond hair.

Ralph Lauren blazers, jackets and button-downs have quickly become a key element of Middleton’s royal wardrobe. She also wore the “Schmitt” herringbone tweed blazer in olive back in April during a trip to Scotland, and the “Capri” striped cotton-poplin shirt in tan and white during a trip to Colchester Hospital in July.

Princess Beatrice attended the BGC Group Charity Day as a representative from CFRF. BGC, a financial group, donates 100 percent of its global revenues to the Cantor Fitzgerald Relief Fund and other charities to commemorate the victims lost on 9/11. The company lost 658 employees on Sept. 11, 2001.
