Simon Porte Jacquemus knows how to put on a show—and dress its viewers in the chicest way possible. The designer from the South of France debuted his spring/summer 2027 collection this week at Phare de la Pietra on the French island of Corsica, and invited some of the most stylish girls from his home country and beyond to watch from the front row. As for what they wore for the occasion, the best-dressed among them seemed keen on donning one dress color and one dress color only: aqua blue, the summer shade that’s been quietly taking over, replacing the likes of regal purple and butter yellow in recent months. It was all over the show venue, setting the tone up for a run of dominance throughout the remainder of 2026.

The most prominent wearer of aqua blue was Alexandra Leclerc (formerly Saint Mleux), whose looks at Jacquemus shows get better every season. This time around, Leclerc wore an aqua-blue poplin dress with a V-shaped neckline and a draped bodice that cinched beneath the knee before poofing out in a mermaid-esque fashion. (See Look 5 from the show.) She paired the dress with light-colored accessories, including an ivory box bag with feather embellishments and a pair of white classic pumps.

Leclerc’s dress was one of a handful of aqua blue pieces featured in the S/S 27 collection. There was also a strapless gown and matching headpiece in the shade, as well as a voluminous skirt and pair of ballet flats. Clearly it’s making the rounds. She also wasn’t the only attendee who wore the color, with others like Ro Brahmand and Quenlin Blackwell also picking dresses in a similarly vibrant and summer-ready shade.
