It isn't mandatory to bring a gift to the engagement party, and most couples won't expect anything. It's understood that guests will have plenty of other gift-giving opportunities, such as the bridal shower, bachelorette party, and wedding itself. If you feel uncomfortable going empty-handed, a bottle of wine, bouquet of flowers, or even just a card is fine. Any gesture is sure to be appreciated by the couple, or ask the host what the best policy is if you still remain unsure.

If you're a close friend or family member and do want to bestow something on the happy couple, don't expect it to be opened at the party. Other guests may not have brought gifts, so the couple should wait until after the party to avoid any embarrassment.
