Business casual
dress code
Business casual is an ambiguously defined Western dress code that is a form of smart casual wear for business purposes, replacing traditional business wear ("informal wear") for white-collar workplaces. For men this consists of some components of a business suit, typically a dress shirt and trousers, but without a matching suit jacket, and with neck ties optional. A coordinating (not matching) sport coat or blazer may be worn, or omitted; a sweater or vest may be worn instead. For women, the same components can be worn (dress shirt, trousers, optional coat etc.), though usually in a female style, like a blouse for a shirt. A dress or skirt may be worn instead, generally at or just above the knee. There is significant variation; see § Definition.
Acceptance of business casual in the United States was preceded by Casual Fridays which originated in California in the 1990s, in turn inspired by the Hawaiian 1960s casual custom of Aloha Friday. The designation of particular clothing pieces as "business casual" may be contentious.
Definition
There is no generally agreed definition of "business casual". One definition states that it includes khaki pants, slacks, and skirts, as well as short-sleeved polo shirts and long-sleeved shirts, but excludes tight or short skirts, T-shirts, and sweatshirts.
This brief starts where responsible research should: with the source description of “Business casual” as dress code. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as dress code. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 7, 2026. The linked authority identifier is Q1021661. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
