Engagement party guests generally opt for simple, inexpensive gifts such as cookbooks, picture frames or wine, explains Emily Post. For informal parties, guests may arrive with wine or flowers, according to Martha Stewart.
The couple may ask the host to pass on to invitees that gifts are not required, says Emily Post. Alternatively, Martha Stewart suggests that the couple may decide to give their parents their wedding registry information to pass along in case someone asks.
Emily Post's engagement party etiquette advises invitees to make gift-giving decisions according to personal finances and levels of friendship. Those who feel unsure if gift-giving is expected may ask the host for guidance.
