A backpack is a very casual bag, and it’s usually not the best choice for the office. Instead, go for a canvas messenger bag or leather briefcase.

If you do prefer a backpack, get one that looks nice with business casual outfits. Consider brands like Everlane, Tumi or Herschel.

What About Casual Fridays?

Just like the business casual dress code, casual Fridays vary widely from one office to the next.

If you work in a formal environment (suit and tie Mon-Thurs), casual Friday usually means business casual Friday. Basically, you can ditch the suit and tie but may still need a jacket (or at least a tucked in shirt).

If you work in a business casual office where men rarely wear jackets or ties, it’s probably okay to wear jeans – and maybe even sneakers – on casual Friday (ask your manager). During fall and winter, any casual boots are probably fine.
