I used to get all gussied up for formal night, including long, formal gown, etc (I started cruising in 1984 when I was 21). Since that time however, age and I guess motivation have seen me dress down for formal nights, i.e. a nice cocktail dress or similar. I used to have DH wear a tux but that was the last DH, lol! The current one wears a dark suit and has always seemed to be dressed just right. I have only sailed Carnival, RCI, and NCL (and a few defunct lines) so I've not been in the company of folks who still dress way up for the formal nights such that maybe Holland or Princess or Crystal would see. I'm getting "comfortable" in my "old age", lol and would really rather wear sweats but don't mind getting gussied up a night or two, gives DH and I a chance to act grown up Besides, this is why we have become balcony addicts, you don't have to wear anything out there if you choose!!!!!
