Dressing Up for Work Is a Thing Again—Why Corporate Girls Are 2025's Most Influential Outfit Inspo

Welcome to the Gen Z Mood, where I—Who What Wear UK's 27-year-old social media editor—keep you updated with my mood of the month and the most exciting things I’ve spotted on the scroll. I'm always looking for new and thrifty ways to shop trends, and I'm taking you with me.

The Mood: Going corporate

As a social media editor, it’s my job to scour the feed for viral moments, figuring out which ones will stick and which will pass us by. Sometimes the moments with influence surprise us –no one would have guessed this summer would be coined “Jet2holiday” summer–but here we are. Beyond Jess Glyne’s viral soundbite and The Devil Wears Prada 2 spoilers filling my feed right now, there’s one fashion trend cutting through the algorithm that seems to be spurring on both Gen Zs and Millennials to rewrite the outdated rules of workwear.

From exploring new takes on tailoring to finding the perfect pair of wide-leg trousers, deciding what to wear to work, specifically among Gen Z and Millennials, is front of mind right now. In the last two months, searches for “chic office outfits” are up 1000% on TikTok and other search terms like ‘OOTD office outfit, “corporate outfits women 2025” and “corporate girlie” are garnering huge numbers across the board—not just on TikTok but Instagram and Pinterest, too. It’s not often a trend soars across all platforms but, in this instance, the usual “Gen Z vs Millennial” trope feels tired, with the two generations aligning on a pursuit for a chicer, more elevated office uniform. Someone who embodies this shift and sits bang in the centre of the generational divide is the content creator simply known as Kat –if you've found her on the scroll–@katfromfinance.

If you’ve been on social media at all in the past few months you’ve probably clocked Kat’s high-fashion selfies shot against the tan wood backdrop and line up of sinks. She’s legit—she does work in finance—but between crunching numbers, she manages to fit in lunch-break photoshoots showcasing her stylish wares (maybe we’d all be at it if our bathroom lighting was that good).

With a growing audience amassing 90k across her accounts and just short of 1 million likes on TikTok, who better to ask for their take on this very specific “corporate girlie” movement. “When I hear , I think of a successful woman who’s got her life together—she knows her deadlines and meets them without fail. She’s bright, bold, and confident, and she always gets what she wants. It’s a look that mixes professionalism with a playful edge, showing that you can be both powerful and feminine at the same time.”

“Over the past ten years, I feel like traditional office wear has been reimagined,” she continues. “Rather than simply conforming to old standards, people are now adding personal touches that make classic pieces—like blazers—feel fresh and elevated. Through imaginative styling and bold accessories, conventional workwear has become a canvas for self-expression. There’s been a real shift from blending in to standing out; professionalism today is less about uniformity and more about individuality.”
