This style’s earned its stripes as a celebrity must-have.

Katie Holmes and Meghan Markle both wore the Posse Theo Strapless Dress ($239 $190) just weeks apart last summer — and right now, during the brand’s End of Season Sale, it’s available for under $200.

The Duchess of Sussex selected the timeless look for a dinner date with Prince Harry in Montecito last August, completing the look with her signature tousled updo and a beaded Cult Gaia clutch.

Meanwhile, Holmes proved it works just as well for a more casual outing, pairing the same design with Balenciaga high-top sneakers the same month.

They’re not the only famous folks shopping the style, as a whole posse of influencers and models — including Arielle Charnas — have also posed in the black-and-white bandeau dress.

Posse’s quickly also earning a reputation as a quiet luxury staple; Sofia Richie famously wore its white Emma Vest ($240) and matching Pencil Skirt ($250) prior to her headline-making wedding last in April.

And Markle’s love for the label has hardly cooled down over the past year, as she styled the same linen skirt with a white knit Argent tank ($145) during her trip to Colombia with Prince Harry this month.

While the star-approved linen look’s not included in the current sale, discounts include similarly luxe-looking options like the Gigi Column Skirt ($290 $175) and Mylah Strapless Dress ($380 $230).

Just be sure to shop fast, as select styles are already flying off the shelves.
