Usually when I travel I want to be as comfortable as possible, so I take more casual relaxed wear. (I pretty much live in casual wear anyway.) However, I'll usually take along a piece or two that can be dressed up or down. That way if DH and I want to have a special date night while there, we can.
Being parents of two younger kids, we don't have too many quiet moments to ourselves, so we try to make the ones we have special. I like to dress up very femininely on occasion too. It's just plain fun. Lately I've been playing around with '30's and '40's style makeup and hair. I just need to find a couple of dresses that fit the period to pull off the look.
