4 night cruise dress code

would it be acceptable for women to wear cropped pants(mid calf length) and nice shirts/sweaters to the restaurants(not the adults only) in the evenings, and young boys (5 yrs old) to wear nice shorts and polos? if not can someone please direct me to websites or stores that I can check out, I live in North Carolina, along the coast.

thanks

We went casual to all the dinners. I dodn't know we were suposed to be a little formal. We were still teated very well!
