Second, many offices allow for very casual Fridays, meaning you can wear your shirt untucked. For example, you might wear jeans or chinos with a casual button up shirt, untucked.

Just make sure it’s the right length. You don’t want to be that guy who just wears his dress shirt untucked like he’s performing some sort of walk of shame.

Of course, when in doubt, just ask your manager what’s appropriate.

Business Casual Shoes

In general, casual shoes aren’t really appropriate for business casual settings. I’m talking about sneakers, sandals, flip flops, work boots, boat shoes, driving mocs, espadrilles, etc.

Almost any type of “dress shoe” is okay, barring velvet slippers or patent leather whole cuts, of course!

The sweet spot consists of:

• Bluchers
• Oxfords
• Brogues/wingtips
• Loafers
• Dressy chukkas
• Chelsea boots

When in doubt, you really can’t go wrong with a more casual lace up (like wingtips) or any kind of loafer.

The biggest mistake I see men make with business casual shoe choice is wearing shoes that are way too casual.

I’ve seen so many guys wearing boat shoes to the office with chinos or even wool dress pants. It just looks…wrong. The boat shoe is way too casual for that type of outfit.

Remember: it’s always better to be slightly overdressed than underdressed, so when in doubt, choose the more formal shoe.

Are Jeans Business Casual?

Technically, no. Menswear purists would never wear jeans in a business casual environment. But many modern offices are okay with jeans, even though this often backfires.
