What is proper attire for christmas spectacular with the rockettes at Nokia in Dallas? -

Some will wear Dockers and a sweater, others in slacks and sports coat and some will wear a suit.All of those are appropriate. Which ever is most comfortable for you is fine.

A suit and tie is too much for me, but if you want to dress nice, that is certainly okay.When I go to special events like a concert I wear Sunday clothes, even if most people are casual.
