My wife did the same! We were on the Bermuda cruise in May and found the daytime dress to be less than we expected. I did not pack jeans or sneakers, instead opting for slacks, slip on dress shoes, polo shirts, sports jacket etc. Surprised to see folks in what I thought to be too casual attire (ie sneakers, jeans, ratty shorts, etc). Someone said it may have had to do with the high number of Americans on board. I just thought it was too understated and not quite the elegant refined look I expected (I'm from Pennsylvania!). Perhaps a crossing has a different feel. I'll be interested in hearing from others.
