The COVID-19 pandemic has significantly changed workwear norms in the UK, leading to a rise in casual dress codes. Data shows that references to casual attire in job postings increased from less than 1% pre-pandemic to 3.3% in July 2025. This shift is influenced by the growing presence of Gen Z and millennials in the workforce, as well as the tech industry's impact on other sectors. Employers are adopting relaxed dress policies to attract talent, reflecting broader cultural changes in workplace expectations.
