The "Office Siren" aesthetic is the latest TikTok obsession. The fashion trend is a new take on business casual, or business-core if you will. Here to bring a hint of sexy back to office-dressing to rock the look add an oversized blazer, pretty fitted blouses, tuxedo style shirts, tailored or wide-leg pants, and chic pencil skirts to your wardrobe. To really give your work look a coquette meets office siren spin add a necktie (yep, ties are on trend for ladies) slinky stilettos or kitten heels, and a structured top-handle bag. While you're at it, add some statement gold jewelry, slinky eyewear, and a sophisticated lazy girl bun, as Sofia Richie Grainge made famous.

This coquette twist on business casual which favors tailored, deconstructed, slouchy, oversized pants and sexy skirt suits was a key trend on the Fall/Winter 2024 runways where designers like Schiaparelli, Kenzo, Victoria Beckham, and Max Mara, all played with corporate style codes, even signaling the arrival of the necktie.
