It’s a spring thing.

During the California heatwave, Meghan Markle stayed cool and casual in a style from one of her favorite brands: Brochu Walker’s Havana Dress.

She styled the breezy design with gold jewelry for her latest As Ever campaign, matching her outfit to a bouquet of white gardenias.

The tiered style is designed to be universally comfortable and flattering, whether cinched with a belt or worn loose and flowing.

In addition to Markle’s pick, it comes in 22 other colors, ranging from neutrals to limited-time seasonal shades like coral and cobalt blue.

The brand also makes a minidress version, plus a matching Havana Cardigan with the same puff sleeves.

To complete the look, consider shopping similarly spring-ready styles like the platform Seoul Leather Sandals or the Cassis Sunglasses — the latter of which Markle wore to a Dodgers game last year.

The Duches of Sussex’s extensive Brochu Walker collection also includes the vegan leather Esme Skirt — which she wore to speak on a panel last year — and the Joseph Top.

But her favorite just might be the Everyday Cashmere Crew, which she’s worn at least nine times and owns in a variety of colors.

She’s not alone in her love for the label, as everyone from Martha Stewart to Julia Roberts has worn its wares. Oprah even named the Looker Layered V-Neck a “favorite thing” in 2024, saying it’s an “an easy way to look pulled together.”

“Our pieces photograph beautifully, travel well, layer effortlessly and feel special without shouting,” the brand’s creative director, Karine Dubner, previously told Page Six Style.

“It’s that subtle elegance, that quiet confidence, that I believe truly resonates.”
