Princess makes it easy to know what to pack and what to wear when you're dining onboard. There are two designations for dress codes: Smart Casual and Formal.
Smart Casual Evenings:
•Passenger attire should be in keeping with what would be worn to a nice restaurant at home. Inappropriate dinner dress such as pool or beach attire, shorts, ball caps and casual jeans (with fraying and/or holes), is not permitted in the dining rooms. Shoes must be worn.
•Evening gown, cocktail dress, or elegant pant suit for women
•Tuxedo, dark suit or dinner jacket and slacks for men
On Smart Casual nights just about anything fits except for the no-nos.

Smart/casual was just like Irish said- anything this side of the no-no's- I only saw a couple folks 'breaking' the rules-- A couple guys wearing jeans and 1 wearing long shorts in the dining room. My husband was a tad overdressed on formal night in a tux- must guys just wore a suit- a couple went with a long sleeve shirt & tie and one dork just wore a short sleeve sport shirt.
The women seem to take it a lot more seriously = from my observations.
