Mens Smart-Casual - Want something a bit different, any ideas? - mens smart dress

It's "Night of the achievements" of the school and the dress code is smart / smart casual .... Most men do pants and a shirt + tie (with the top button to make it less formal), but I want to make a slightly different ... So you have any ideas? Good color combinations, etc. ...? anything but a shirt and tie? Reply ... However, they are strange .. Thank you (:
