I was on the recent May 19 Oasis sailing and I wore jeans and an untucked polo to the American Icon (main dining) on the first formal night, my son wore something similar, and my wife and daughter were not dressed "formally" and we had no issues. We went to Sabor on the other formal night so I can't speak to the latter formal night.
