Casual, some people are very chic but must people are dressed "normally "
Casual or fancy either is fine. It's nice to dress fancy once in a while so I'd take advantage of the opportunity. There is a security checkpoint so keep that in mind. The show is great! Enjoy!
Dress your Christmas best, your in the greatest city in the world.
Comfortable... Casual is fine. It's a good show. I saw it 2 weeks ago. Also you'll need to empty your pockets to go through a metal detector.
You can go smart or casual or sparkly - there is no discretion but since it's a Christmas event it's worth getting in the spirit with some festive attire.
