I thought I was the only one that said "that would be great for the cruise!!" Not only do I say it, but my girls (8yr and 12yrs) have been known to say " mom, that would be good for your cruise!"
Also, after the holidays there are great sales on formal wear that is not too heavy for cruising. I get a lot of wraps, purses, dressy shoes etc. Usually 50-75% off!!
