We are not "formal" and our wedding will be classy but I wouldn't call it formal. It's in the afternoon and the men aren't wearing full tuxes/ suits. It's not backyard BBQ casual but somewhere in between.
1. Do I have to put titles on the envelopes? Mr. & Mrs. Joe Smith or can it just be The Smith's or Joe & Mary Smith?
2. Does the male always come first? I have a lot of unmarried female friends that I'm inviting so it seems weird to send it to Joe Smith and Mary Jones when Mary is really the one I'm inviting and Joe just happens to be her date/ boyfriend. I would find it odd if my friend sent my invitation to Jenna's Fiance and Jenna. Feels like I'm the plus one.
