Business formal means a full suit, a white or light blue dress shirt and a tie. Business casual drops the suit and usually the tie: a collared shirt, smart trousers or chinos, and leather shoes. Smart casual is the most relaxed: neat shirts, dark jeans or chinos, loafers or clean sneakers, and more freedom with colour and pattern.
Here is exactly what each dress code means for your shirt, trousers and shoes, so you never turn up under- or over-dressed.
At Aldeno, whichever level you need, you can start with the right shirt from our business formal shirts.
Key takeaways
- Business formal: a suit, a dress shirt and a tie.

How to decode an unclear dress code
- "Formal" or "business attire" on an invitation means business formal.
- "Business casual" or "office attire" means collared shirt and trousers, tie optional.
- "Smart casual", "cocktail casual" or "dress to impress" means polished but relaxed.
- When in doubt, dress one level up. You can always remove a tie or a blazer.

Frequently Asked Questions
What is the difference between business formal and business casual?
Business formal requires a suit and tie with a white or light blue dress shirt. Business casual drops the suit and makes the tie optional, allowing chinos, button-down collars and softer colours.
Is smart casual the same as business casual?
No. Smart casual is more relaxed: dark jeans, oxford or linen shirts and clean sneakers are acceptable. Business casual still expects formal trousers or chinos and leather shoes.
Can I wear jeans for business casual?
Usually not in traditional offices. Dark, well-fitted jeans are better suited to smart casual. Some modern offices allow jeans on Fridays.
Do I need a tie for business casual?
No. A tie is optional for business casual and required for business formal.
Is a button-down collar business formal?
A button-down collar is better suited to business casual and smart casual. For business formal, choose a spread or cutaway collar.
What should I wear if the dress code is unclear?
Dress one level up. A suit or blazer with a formal shirt is easy to dress down by removing the tie or jacket.
Conclusion
Business formal means suit and tie, business casual means a collared shirt and smart trousers, and smart casual means polished but relaxed. When in doubt, dress one level up; it is always easier to take a tie off than to add one.
