I thought the purpose of a cruise was to relax and enjoy life. During the day I read that shorts and a T are perfectly acceptable. Why does that become unacceptable once the sun goes down? I live in Texas and I wear T-shirt, shorts, and Tevas pretty much 24/7 unless the temp drops into the 50s or below when jeans and sneakers become comfortable. (I am very warm blooded I guess.)
I have never been on a cruise before, but I am stressing about taking one as I am very uncomfortable in slacks and dress shoes. I don't mind wearing a collared shirt if its not to hot, and I assume it would be cool enough at night, but my feet really bother me in almost any kind of shoe for long periods of time.
