Casual wear ( casual attire or clothing) is a Western dress code that is relaxed, occasional, spontaneous and suited for everyday use. Casual wear became popular in the Western world following the counterculture of the 1960s. When emphasising casual wear's comfort, it may be referred to as leisurewear .

Employees may wear more relaxed, informal clothing but not necessarily what they wear on the street or lounging at home. For example, a casual dress code may let employees wear jeans every day but still discourages sweatpants. Companies can set specific guidelines within their dress code policy to ensure employees wear appropriate attire.

While casual is " informal " in the sense of "not formal", informal attire traditionally refers to a Western dress code associated with suits - a step below semi-formal attire - thus being more formal than casual attire.
