When it comes to buying a wedding gift, try not to overthink it! Keep it simple and pick a gift off the registry. You may think that’s boring, but the couple knows what they want and need better than you. Unless you are extremely close to them, and can make it more personal, just get them something they ask for.
If the registry is dried up, then, as lame as it may sound, I’d recommend cash or a gift card.
