I was invited to dine at home should have flowers, wine or chocolates to hand. (Do not remove it because it is Chrysanthemum flowers used in funerals).
If invited to dinner at home should be copious wine or chocolate stuck with hands (don't remove any flower, chrysanthemum flower, it is to apply only to the funeral).
If you have received an invitation to dine at home should have a flower wine or chocolate, in her hand. (don't chrysanthemum to strictly because it is used only in the flower funeral).
