In 2025 the line between “business casual” and “smart casual” is blurrier than ever - but showing up in the wrong outfit can still tank your impression. This definitive guide breaks down the exact differences, real-world examples, acceptable brands, and outfit formulas so you always look sharp, modern, and appropriately dressed.
The One-Sentence Difference
- Business Casual = Office-appropriate without a full suit (think “I could meet the CEO or a client”).
- Smart Casual = Elevated everyday (think “creative industry networking event, nice dinner, or wedding guest when it says ‘cocktail’ but not black-tie”).
