When I first started cruising, I did the tux thing but it got tiring. My last cruise was a 3 nighter and there was 1 formal night. Really????? For the last 15 cruises or so I wore a suit or shirt and tie which was fine with me. As we are going on a transatlantic in about 1 month (my first TA btw) I thought it might be fun to revisit formal nights. I rented a tux to have ready in my stateroom with the shoes and am actually excited. I'll let you know how it works out!
