You know, there is suggested wear codes, but very few follow. On our last cruise on HAL I was surprised on how few did follow code.
Out of our last 4 cruises, we took one with HAL, and 3 with NCL. NCL's "suggested"dress code is the most lenient of all 7 lines I have cruised, but I have found people actually dressed better overall.
I think these suggested dress codes must bring out the "rebel" in people.
Myself, I never cared for going to dinner in shorts, even if it was only Cracker Barrel. I never have had trouble following suggested code or felt it was an inconvenience.
There are nice short sets that are inexpensive, but look well, so I have no problem seeing others in shorts, now that most lines have relaxed their code to include shorts.
However,what shocked me the most ever, was on HAL, there was a girl around 20 in cutoffs and a halter top at dinner on formal night near us in the dinningroom.
