No, it is not. A black tie event insinuates that tuxedos or very nice suits are the proper attire for the occasion. So men should be expected to dress like that, and women shouldn't wear short skirts or sleeveless dresses.
A Black Tie event means you hav to wear a tux but maybe this isnt a black tie event, Definateley a suit with a Tie or Bow Tie and dress pants dress shirt. If i was you i would wear a Tux with a nice tie. If you dont have a tux BUY ONE, Youll need one soon anways.
White bow ties are worn with morning coats of varying colors. Evening wear requires a black coat and black tie. A man's evening wear is meant to keep him from clashing with his partner's gown, so black and white are preferred.
