While we were spending Christmas with FH's family (immigrated from Russia, for backstory) the topic of the wedding was brought up. They haven't been involved in the planning because FH doesn't get along well with them, so we are pretty much done with everything at this point....
His aunt asks what my colors are (Purple and Ivory) and his mom, sister and grandmother get upset and start talking about how purple is not a color for weddings it's for funerals and it will be bad luck and end in divorce. I have never heard anything like that (but my FMIL also gave everyone a coin and a fish scale at Christmas to keep in our wallets to promote wealth so...)
The discussion got rather heated between my FH and his mom so it was dropped. What other strange superstitions about weddings have you heard (other than the traditional "bad luck to see the bride before the wedding" stuff)?
