I had not seen anyone wearing tux during prom day/night.
A tuxedo is the height of formal wear dressing for a man. Knowing when to wear one and what type to buy or rent can be a little trickier. Here's some help:
When to Wear a Tuxedo
* When the invitation states Formal, Black Tie, Black Tie Invited or Black Tie Optional
* To the opening of the opera, ballet or symphony
* Ball or formal dance
* Formal dinner party or reception
* Dinner at a formal restaurant (some folks think you should be dressed at least as well as your waiter)
