Couples who are meant for each other almost always have something of a vibe. So the question to ask before any wedding—long before details about what to wear and what sort of toast to give—is simply: What kind of couple are they? Are they always out on their tricked-out catamaran or huddled over a table at romantic restaurant? Are they throwing epic parties, conquering mountains, or Netflixing and soaking in the tub at home? Know your couple and setting them up with the perfect gift is easy.
