Michelle Monaghan’s Dress Has Just a Whisper of Mermaid Fantasy

If the best-dressed stars of summer 2026 have demonstrated one thing, it’s that bras can be the centerpiece of any outfit. Michelle Monaghan is the latest to prove exactly how.

On Monday night, the actor arrived at the New York City premiere of Netflix’s The Whisper Man wearing a Bevza dress that put a mermaidcore spin on bra-first dressing. Aptly named the Mermaid Bra Dress, its body-hugging black column skirt was contrasted by a cream-colored bra with subtle ribbing that emulated the texture of seashells. At the back, its streamlined silhouette featured a high slit, allowing for effortless movement as she walked. Styled by Karla Welch, Monaghan accessorized with Gianvito Rossi’s Portofino Sandals, drop earrings, and a perfectly on-theme pearlescent manicure.

While peekaboo styling has been rising in popularity for seasons, this summer saw the undergarment evolve into the main event for a subset of fashion-inclined stars. Anya Taylor-Joy experimented with bright color-blocking in a Balmain look. Kristen Stewart went bra-first in a tweed Chanel set. Ravyn Lanae used a Versace spiral bra as a conduit for surrealist dressing. Monaghan’s mermaidcore take, however, is both ethereal and decidedly restrained.

For her latest role in The Whisper Man, the 50-year-old actor will star alongside Robert De Niro and Adam Scott. The film—streaming on Netflix on August 28—is a dark crime thriller surrounding a serial-killer mystery. It makes sense, then, that to promote the upcoming release, Monaghan would offer a more muted interpretation of the bra-as-the-outfit style. Once intended to be layered under clothes, the brasierre has emerged as a staple of styling experimentation and sartorial shapeshifting. It’s no longer synonymous with festival dressing or pop-star maximalism. Clearly, when done right, the bra can even be a dress code for the macabre.
