Smart casual is an ill-defined dress code that is generally a neat yet informal attire. The locality, type of event, context or culture constitutes the various interpretation of the dress code and therefore the designating of certain clothing pieces as smart casual is disputed—for example, jeans.
Australia‘s national dictionary Macquarie Dictionary defines smart casual as „well-dressed in a casual style”.
Oxford defines it as „neat, conventional, yet relatively informal in style, especially as worn to conform to a particular dress code”.
Dictionary.com’s 21st Century Lexicon defines it as „of clothing, somewhat informal but neat”.
