When it comes to hosting an event in the afternoon, you may want to mix up the term "afternoon reception" with a few other synonyms. If you're having a ceremony or celebration in honor of an occasion happening earlier in the day, you could opt for "tea party" or "post-luncheon gathering." If you're going for a cozier vibe, "afternoon tea," "open house," or "cocktail party" may be a better fit. For events with more business-esque vibe, consider "networking reception" or "corporate mixer." Of course, you can always get creative and come up with a title specific to your event's theme or purpose.
