Tailored fits, light makeup and sleek hairstyles sound like a boring office dress code. Not anymore! Following TikTok's "office siren" trend, high-fashion corporate looks are now taking over, reinventing the vintage style of the '90s and 2000s. Today, the office siren – the opposite of a shy librarian girl – is the ultimate girl boss who embraces her status with inner confidence and curtsies.

While most bloggers are trying to come up with outfit and makeup ideas for the new trend, some hair enthusiasts are taking matters into their own hands to channel the office siren. They elevate classic low buns with claw clips and pencils to match the business vibe. Here's everything you need to know about the new hairstyle craze!

Remember Giselle Bündchen's iconic look in her cameo “The Devil Wears Prada”? Yes, the one with an all-black formal outfit, save for sky-high heels and a colorful necklace. This is exactly what the office siren looks like. A sleek updo, natural makeup and Bayonetta glasses complement the look, making it a bit sassy yet formal enough to attend the office meeting.

And whenever she enters a room, she acts as if the entire space is hers. So basically an office siren is a fashion queen who uses her workplace as a catwalk, yet still retains all that bossiness and professional excellence.
