I lurked a lot on these boards for my own wedding and am thankful I'm did. There were a few things I felt might be rude but wasn't sure and it was nice to get confirmation here. I am so thankful that I was able to avoid any etiquette blunders for my own wedding but now sometimes I wish I didn't know so much about etiquette because I see infractions everywhere!
For starters I don't think I've ever received an invitation without registry info included. I Just received an invite yesterday for a coworker of my Husbands. They put "Adults only" no less than three places. The actual invite, the direction card and the RSVP card. Yikes! They also included registry info. The good news is, according to H, there will be an open bar and plenty of food. I try to give people the benefit of the doubt about some stuff ie. adult only reception, registry info, and chalk it up to them not knowing any better. It's just hard not to side eye when you know they are being rude. KWIM?
I have a friend who's getting married in September who tends to be a little oblivious.If she asks me for help/advise with the invites I'd be happy to help but don't want to be rude giving my unsolicited advise. I'm just hoping her Invites won't include anything cringe worthy.
