Do you get a gift for the bride and groom if you are only invited to the reception?

It is quite common and acceptable to attend a wedding without bringing a gift with you. Many people give the wedding gift before the wedding, and some give it after the wedding. So if you've already given the gift, or plan to give it later, it is perfectly find to attend the wedding without bringing a gift with you.

And if you simply can't afford a wedding gift, then don't worry about it. A wedding is about the bride and groom wanting their family and friends to share in their happiness and the celebration of their marriage, and shouldn't be all about inviting guests just so they will get more gifts.

If I ever felt someone invited me to a wedding simply to get a gift, I would not go to the wedding, nor would I get them a wedding gift.
