I have never really understood the dress request in the less formal dining rooms like Animator's and Parrot Cay. When we dine there, I do let my DS who is a teen wear shorts, even athletic ones with a nice t-shirt. Yup-I'm that mother! He wears nice pants in the more formal dining room and a suit on formal night. He is polite, well behaved, and can keep up a nice conversation. On our last cruise, there was a table that IMO had way too much to drink. They were dressed nice and within the dress request but also loud, obnoxious, and using language, while not completely foul, I'd rather my children not hear. One guy was groping his wife at the table which the head server did try to stop. So as far as I am concerned, as long as my children are wearing clean, no holes, nice clothing, and behaving in a way that makes me proud, I am fine with what they choose to wear. By the way, my DH and I dress as requested by DCL.
