There will be two formal nights, and if you eat in the main dining room, the suggested dress code is jacket & tie for men (some wear a tuxedo), and for women it's dressy stuff (technical term). On non-formal nights, it's casual - Dockers, sport shirts, etc., but no shorts in the dining room at dinner.
In the buffet it's pretty much come as you are, although shirts and shoes are required.
Your cruise documents will give you a more appropriate description than I did. Enjoy!

It's exactly as Pootersdad described. Some people have a real aversion to having to dress up on vacation. For those people, Horizon Court is great or evening ordering dinner in your cabin (it's nice to have a meal out on the balcony).
Princess has made the dress code very easy: 7 day cruise = 2 Formal Nights and 2 Resort Casual nights - this applies to the main dining rooms and alternative restaurants. Buffet is always casual.
Formal - Men - dark suit, tux or suit separates, dress shirt, tie, dress shoes
Ladies - long dress,long skirt w/dressy top, dressy cocktail dress, dressy suit, dressy pantsuit, dress heels or sandals.
Casual - Men - docker type pants with a collared jersey ( polo shirts), hawaiian print
shirts are very popular, casual shoes
Ladies, - dockers type pants with a collared jersey or casual blouse, sundress,
capris, casual skirt & blouse, flat sandals.
Shorts are allowed in the dining rooms for breakfast and lunch and at the buffet.
I'm sure that was a typo - 2 formal and 5 casual is the norm on a 7 day cruise. On longer cruises of 14 days or so, it is 3 formal nights and the rest casual. I think this is a good idea because it still gives the ladies a night to dress up while allowing the gents to be casual on the rest of the evenings.
Why is it that we all over pack??? Just thinking about packing all that stuff wears me out :-) Its nice to get dressed up though. Every cruise I come back with outfits I didn't wear and say never again will I pack sooo much, but you know what happens!!
That is a good question becuause we also do the same thing. (NG) Someone once said after packing, one should go back and take half of what is packed, back out of the suitcases.
In my wife's case, part of the fun of cruising is buying new clothes for the trip. Then she has to pack them all as you can imagine. Just think how far ahead of the game I'd be if she only bought half of what she buys for a cruise. (G)
