My grandma has very severe allergic reactions to any kind of perfume. She has had this for years, but it has gotten much worse in the last few years. It gets to the point where she will have to leave restaurants, church, etc. I guess me question is, would it be tacky if I included an insert with the invitations that said something like "Due to allergies, please no perfume." I obviously don't want my grandma to have to leave any of the festivities of the day, and I don't want to look tacky either. Any suggestions on how to deal with this? Thanks everyone. Your advice is super appreciative.
