As many dos as the office-siren look has—Bone Cuffs, slinky blouses, pencil skirts, stilettos, and cherry red—it likewise has its don’ts, Bieuville shares. One common misconception when it comes to the trend is that it’s vulgar, especially for an office setting. “A big ‘don’t’ for me would be to be inappropriately dressed,” she says. “The corporate side is still very much present, but [the office siren] lifts it all up with a play on materials, and in the end it’s quite a subtle balance.” Putting an emphasis on the word subtle, she says that ending up in anything leopard print with patent-leather stilettos is a sign you’ve gone way too far. “The aim is not to be noticed only for your looks, but to shine with all your qualities.” Really, it’s more about the woman than her closet. Though, when someone has themself fully figured out, they usually also have a good grasp on their personal style. And the office siren is 100% the type to know exactly who she is and what she wants—from her job, from her style, from her life as a whole.
