Dress Code on Magica?

I am packing stuff for my first cruising and am curious to hear some info about dress code on Costa Magica I will be cruising with this ship for about 7 days or so and I would prefer wearing casual clothes only but it is just that I have heard about some dress code there? So what does that mean?

Well it means that in certain situations there on board you will have to respect some dress codes such as not entering the dinning room in swim suit for example or even in something that is too much casual. So in general you will have to wear shirt upon each dining room entrance except in cases when you decide to frequent some outdoor restaurants there to have lunch or something like that. And basically this dress code mostly to some organized entertainment program that are very common on Costa Magica as on any other cruise ship I guess so make sure you bring at least 2 suites.
