I am getting married and on a tighter budget right now. One of my friends is getting married. I just bought her an expensive gift for her bridal shower. I just got an invite for her bach party with her underwear sizes. Am I correct that I am only supposed to purchase one gift? I don't need to bring a separate gift for the bach party since I was at the bridal shower, right? This is the 4th pre-wedding party for this girl.
