On Thursday, Prince Harry and Meghan Markle greeted a group of young leaders from Commonwealth countries, including Australia, New Zealand, and Fiji, at London’s Marlborough House. In the latest public appearance from the royal couple, the Duchess of Sussex looked like the picture of summer while wearing a sunny canary yellow dress by Brandon Maxwell.

This is the first time Meghan has worn a look by the American designer, and it seems like the Meghan-effect is in full swing as the sleeveless dress has already sold out online. Even though the bright color is a departure from Meghan’s recent penchant for pastel shades, the Duchess’s look was one of her most minimal ones yet, as she paired the dress with nude pumps, tiny stud earrings, and her engagement and wedding ring. Summer simplicity at its best.
