My future mother in law has a seizure disorder and one of the triggers is perfume/cologne, even heavily scented lotions, etc. Heavy perfumes can also be a migraine trigger for my fiance. So, needless to say, it is very important that everyone attending the wedding is aware of this. I'm wondering what is the best way to inform my guests not to wear perfume... I've read elsewhere to include an insert in the invitation, and also spread the word via word of mouth. Any ideas on the most appropriate way to do this and how to word it would be much appreciated! Thanks!
