Well we too love formal nights, as we simply don't get a chance to dress up anymore, and for whatever reason Frank loves his tux. For the other nights he just brings pants that will mix with different shirts and maybe one jacket, which he too wears on the plane.
But I have noticed how creative many of you frequent cruisers are and am impressed and in fact have been trying to mix and match more to bring a little less. I even have three reversable skirts that are very lightweight and just bring a mixture of tops that can be dressed up with some jewelery or a jacket, or just wear them as is for a more casual look.
I too think Ken always looks great, in fact I don't think I've seen anyone in an LCT group that wasn't dressed appropriately and looking great whatever the dress code is. :)
