Hi - I'd suggest you post on the NCL board (maybe you have - my bad).. But with Freestyle there are no formal nights and pretty much anything goes. Most cruisers dress business or resort casual though (I think). You might want some fancier attire for the specialty restaurants if you want to try them and enjoy a nice evening.
Have fun on your cruise.

I posted my formal attire question and got good advice. I am also checking
out the pictures of other cruisers to see what they are wearing. I am also going to ask the person who we booked the cruise with.
