FI and I have been invited to a wedding this spring and I'm kind of torn on what to have him wear. The invitation says Black-Tie. However, from both knowing the couple and what has been indicated on their invitation, it does not meet all the criteria (the bride and I have been casually emailing back and forth with our planning stuff). I nonchalantly mentioned that FI and I would have to find a time to go get him measured for a tux since he doesn't own one, and she said it would be fine for him to wear a black suit. The wedding is at a historic building in a park, ceremony at 5 with an outdoor cocktail hour and indoor multi-course dinner.
There were several etiquette breaches in their invitation which I can overlook because they really are wonderful friends, but it doesn't help me figure out whether or not I should have FI rent a tux or not. The invitation style and wording definitely don't scream Black-Tie but is that enough of a reason for us to skip the tux?
ETA: Why is my font all wonky??
