I am planning to go on a 7 day Eastern Caribbean cruise on Carnival in late March/early April with a couple days before and after spent in Florida. This will be my first cruise. Are there any fabrics that I should avoid. I already have my tuxedos(I am dressing these down a bit while still showing my unique style) picked out, but am looking for a sport coat or two that I could wear during the day or evening. Also, I need some advice on casual wear. I typically wear polos and golf shirts, as well as a few hawaiian shirts here and there, during the day, but advice on other options for both shirts and shorts/pants would be helpful. Quantities needed of both shirts and pants/shorts would also be appreciated.
