Hi PJ,you sound so much like me lol.We took our first cruise in 2001 and I was so obssessed with having the right cloths and what I needed to take with us that I nearly drove my husband batty!I had three suitcases for me and two for hubby...not counting our carry ons.And one suit case had nothing but shoes in it.I am the type of person that likes my shoes to match what I am wearing.
Let me tell you now that I used only half of what I packed.Pack lightly,with outfits you can mix and match.And I found out just as Karen said,that there will be variety of styles on all nights.
My husband hates to wear a tie and refused to dress formal for any of the nights.And he was just fine and not out of place at all. I love to dress so it was fun for me but I still didn't need so much stuff!!!
It takes alot of fun out of the experiance if you are worrying about all that!!!! Relax and enjoy your vacation.
