We are heading on the Crystal Symphony for the mid-December Caribbean sailing from Ft. Lauderdale. It's our first time on Crystal. As we are preparing to pack I (Jake) am trying to coordinate my formal wear vs. casual wear for the trip. I have my formal wear lined up for the formal evenings but I am trying to put together my "casual" clothes.

Ideally I would wear a long sleeve sports shirt (Polo, Liz Claibore etc) with a pair of slacks. I assume the would be appropriate...correct?

Also, what about a "designer t-shirt" with a blazer on top.

Thanks.

Jake
