Hell yes. Have two and wear them a lot. (had a 3rd which I wore well past its usefulness and was loathe to let go)
I have heard that, but don't believe it. Everyone gets invited to a black-tie wedding at some point.
It makes perfect sense for someone to save the money and not buy black-tie and make do without or rent the one time you need it. But the list should have it. Whether to or how to follow the list is an individual choice, but the list should be complete. Or add "if necessary"
I can't believe all these people who never go to black tie, particularly coming from some who apparently run in otherwise formal circles. I have at least 2 black-tie gala events a year, and have been to 2 black tie (or optional) weddings within the span of the last 2 years. I'm in my mid-30s.
I have never (and I'm pushing 50) been invited to a black-tie event, and given my social circle, likely never will be.
