Smart casual is an ambiguously-defined dress code that is generally a neat yet informal attire. Different localities, kinds of events, contexts, or cultures can have varying interpretations of the dress code and therefore the designation of certain clothing pieces (such as jeans) as smart casual is disputed.

Smart Casual is the debut album from Kids in Glass Houses, recorded during late 2007 at Long Wave Studios with Romesh Dodangoda. The album contains songs the band have written since the release of their five-track EP "E-Pocalypse!", and also three tracks from the EP.
