Power Casual: How the UK is Redefining Office Style

Power Casual: How the UK is Redefining Office Style

October 31, 2025

Nearly half (45%) of UK office workers say their wardrobe is more formal now than a few years ago

As more people head back into the office, wardrobes are undergoing a transformation. Across the UK, employees are now embracing a smarter yet more relaxed approach to dressing. As the landscape of office fashion evolves, employees are increasingly investing in clothes that reflect their personal style while still meeting workplace expectations.

A new survey from off-price retailer TK Maxx shows office staff are updating their wardrobes to reflect the modern workplace, and investing money in their workwear wardrobes doing so, viewing their office wear as investment pieces: stylish, adaptable, and, above all, comfortable. This shift is driven by hybrid work patterns, with over a third of employees (38%) spending more days in the office than last year.

Among younger professionals (aged 16–34), most say their wardrobe is now more formal, while this rises even higher among senior staff (C-Suite and Senior Management). But while office wear is getting smarter, comfort still rules — nearly half say it’s their top priority, ahead of looking professional or even dressing for the weather. Over a third also admit that switching between home and office makes outfit choices “more confusing.”

Overall, 45% of office workers are dressing more formally than before — but “formal” has evolved. Today’s professionals are mixing “Smart” and “Smart Casual” styles, with versatile pieces like blazers bridging both worlds to deliver polish and practicality.

Workwear is a key investment for many: 72% of employees buy clothes specifically for the office, with 40% maintaining a dedicated “work-only” wardrobe. Younger workers are particularly likely to keep office attire separate from casualwear, with an average spend of £119.75 per outfit. Men invest considerably more (£141) than women (£99).

For many, workwear is about more than just appearances. Many of us enjoy dressing for work as a way to showcase personal style, while the right outfit motivates us for the day ahead. 

We teamed up with TK Maxx to get their tips for modern workwear:

  • Invest in versatile staples: Timeless pieces like blazers, tailored trousers, and crisp shirts can be mixed and matched effortlessly.
  • Choose comfort with polish: Breathable fabrics, stretch fits, and smart silhouettes keep you comfortable from desk to dinner. 
  • Add personality with accessories: Statement jewellery, bags, or shoes can elevate even the simplest outfit.

With big brands and quality workwear at up to 60% less than the RRP, TK Maxx certainly makes it possible to refresh office wardrobes affordably, keeping style, comfort, and versatility front of mind.
