Dining Etiquette
If invited to an Italian house:
If an invitation says the dress is informal, wear stylish clothes that are still rather formal, i.e., jacket and tie for men and an elegant dress for women.
Punctuality is not mandatory. You may arrive between 15 minutes late if invited to dinner and up to 30 minutes late if invited to a party.
If you are invited to a meal, bring gift-wrapped such as wine or chocolates.
If you are invited for dinner and want to send flowers, have them delivered that day.
