I was researching what I would need to pack for my upcoming cruise on Norwegian to Bermuda and I found this in the attire section:

Bermuda shorts with knee high socks, or Scottish kilts with knee highs will also be allowed in all dining rooms in Bermuda as these are considered formal dress in Bermuda.

Their requirements for the evening meals say things like no shorts, bare feet, etc., but I thought it was interesting they would specifically mention kilts.

I'll have to admit, I also found the following a bit humorous:

Blue Jeans will be allowed in all dining rooms on all Houston departures, due to the Texas culture.
