errrrrr Ally you are missing the point completely. There is a dress code on these ships for dinner in the main dinng room ie casual, smart casual and formal. It is not meant as an option it is a guide as to how you are to dress on these nights if you wish to dine in the main dining room. Im not judging anybody but formal nights are part of the cruise culture and if you dont wish to partake then eat elsewhere and stop spoiling it for everyone else. It kind of ruins the effect if youre in your long dress and jewellery and some idiot at the next table is in jeans and a short sleeved shirt. As i said before you are completely missing the point.
