So, I have a few single girlfriends (and a few guy friends, too) coming to our wedding. All of them got +1's, of course. Do you think it's cool for them to bring just a friend of the same sex? I think it's totally fine, and my FI thinks it's weird. I mean, they're not all dating someone and I'd never expect them to travel alone. I went to my girlfriend's wedding in Vegas and brought a girlfriend with me. Granted, I was like 22, but still.... Just curious on your thoughts!
