A white polo and white shorts are the kind of a never-failing off-duty outfit that you so awfully need when you have no time. To bring out a more easy-going side of you, finish with dark brown leather sandals. So if it's a blazing hot warm weather afternoon and you want to look dapper without exerting much effort, this look will do the job in no time flat. This combo shows that hitting 30 is no reason to shed casual style altogether.
