Because nice slacks are allowed on both nights. I just paired it with nicer blouses on informal nights. I did a 12 day with Celebrity to Alaska. I hope that helps.
This does vary by destination, but my experience is that passengers on most of Celebrity's longer cruises tend to dress on the dressier side of the published standard rather than on the more casual side of the published standard. In particular, I have seen a lot of very nice cocktail dresses on Celebrity's "informal" evenings. This is especially true of cruises within Europe and on Transatlantic cruises.
