Business Casual for Men: What to Wear, What to Skip, Five Outfits
Business casual for men means a collared shirt, chinos or wool trousers and leather shoes. No tie needed. A blazer is optional. It’s dressier than weekend clothes and more relaxed than a suit. Every workplace draws the line a little differently, so start with the basics below, then match what the people a level above you wear.
An open collar shows fit more than a shirt under a tie does. Get your collar and sleeve size from the size calculator first.

The business casual formula
| Piece | Good choices | Skip |
|---|---|---|
| Shirt | Oxford button-down, poplin or twill dress shirt, knit polo in some offices | Graphic tees, tank tops, worn-out flannel |

| Layer | Blazer, sport coat, sweater, quarter-zip, cardigan | Hoodies, athletic jackets |
| Shoes | Loafers, derbies, oxfords, chukka boots, clean leather sneakers in relaxed offices | Running shoes, sandals, flip-flops |
| Belt and extras | Leather belt that matches your shoes, simple watch | Loud belt buckles |
The best shirts for business casual
The shirt does most of the work. Three styles cover almost every business casual office.
- Oxford cloth button-down (OCBD). The classic. Slightly textured, sturdy and fine untucked or tucked. Read our oxford shirt guide.
- Poplin or twill dress shirt, no tie. Dressier. Works with a blazer for meetings. See shirt fabric types for the difference.
- Knit polo. Fine in many offices in solid navy, gray, white or black. Not for interviews or client days.
Colors that always work: white, light blue, pale pink, light gray, and subtle stripes or checks. Get the size right first with the size calculator, because an untucked or open-collar shirt shows fit problems more than a shirt under a tie does. Then check the fit guide to pick slim, classic or athletic.
Five business casual outfits
- Light blue oxford button-down, navy chinos, brown leather belt, brown loafers.
- White dress shirt, gray wool trousers, navy blazer, dark brown derbies.
- Striped poplin shirt, khaki chinos, navy crewneck sweater, suede chukka boots.
- Navy knit polo, charcoal trousers, black leather sneakers (relaxed offices only).
- Pale pink oxford, dark jeans (if allowed), gray sport coat, brown loafers.
Business casual vs smart casual vs business professional
| Dress code | Jacket | Tie | Typical shirt | Trousers |
|---|---|---|---|---|
| Business professional | Suit | Yes | Dress shirt, point or spread collar | Suit trousers |
| Business casual | Optional blazer | No | Dress shirt, OCBD or polo | Chinos or wool trousers |
| Smart casual | Optional | No | OCBD, knitwear, polo | Chinos or dark jeans |
| Casual | No | No | Anything clean | Jeans, shorts |
If the event or office says business professional, wear a suit and tie, like you would for a corporate job interview.
Business casual in summer and winter
- Summer: lighter chinos, linen-blend or seersucker shirts in casual offices, unlined loafers. Long sleeves rolled once look sharper than short sleeves.
- Winter: flannel trousers, merino or lambswool sweaters over a collared shirt, leather boots, a wool overcoat.
Keep it sharp all day
- Iron or steam your shirt. Wrinkles read as careless faster than any style choice. Here’s how to iron a dress shirt, or try non-iron shirts.
- If you untuck a shirt, the hem should end around mid-fly. Longer than that, tuck it in.
- Deal with underarm stains early. See how to remove sweat stains.
Next step: find your collar and sleeve size, then compare brands that sell it.
Quick answers
Can I wear jeans for business casual?
Only if your workplace allows it. Dark, clean, well-fitted jeans with a collared shirt and leather shoes are business casual in many offices, but in more traditional ones they aren’t. When in doubt, wear chinos.
Is a polo shirt business casual?
In many offices, yes, especially a solid knit polo in a dark or neutral color. For client meetings or interviews, a collared button shirt is the safer choice.
Do I need a blazer for business casual?
No, but it helps. A navy or gray blazer turns a shirt and chinos into a dressier outfit for meetings, and you can take it off at your desk.
What shoes are business casual for men?
Loafers, derbies, oxfords, chukka boots and clean leather sneakers in some offices. Skip running shoes, sandals and worn-out boots.
What is the difference between business casual and smart casual?
Business casual is office wear: collared shirt, chinos or trousers, leather shoes. Smart casual is a step more relaxed and used for social events, so dark jeans, knitwear and clean sneakers are more common.
