I agree with all the hearty "yes" to the original question. But I saw another post here which suggested that one should not wear a long dress to a wedding. So I googled it and found this article. It says nothing about long dresses, (if anyone knows of such a rule, please let me know) but the first two rules of this article are "no black and no red". There is also a rule for the grooms ex-girlfriend for which I must ask, how on earth did she get an invitation?!
Some people are still friends with ex-boyfriends/ex-girlfriends! I imagine there will be a few exes on both sides of the aisle when I get married.
Ditto. I've been to the weddings of exes and will have at least a couple of my exes at my wedding. I don't see it as a big deal.
My maid of honor introduced me to my husband when he was her date and instead of a best man he had a best woman who happened to be an ex.
It isn't that odd that an ex would be invited to a wedding.
