Q: If you are invited to a wedding where the invitation specifically states ‘Black Tie’ then you have three choices to make. You rent a tux, you buy a tux, or you do not attend. Is that correct?
A: Yes. You are correct, if you don’t have a tux and cannot or do not wish to rent a tux you should not attend the wedding. If black tie is optional it will be stated as “Black tie optional” in which case you may wear a dark suit with a white shirt and conservative tie.
