Not sure if this is a custom or tradition but I didn't know where else to put this.
Two days before the wedding is the mother of the bride's birthday. The day before is one of the bride's closest friends'/he's singing at the wedding birthday. The day of the wedding is one of the groomsmen's birthdays. Since they will all be at the rehearsal dinner we would like to do something small to acknowledge the birthdays because that's what we would do if it wasn't our wedding day! But I'm not sure how to do it. I'm thinking of having shirts made that say something like "it's my birthday and all I got was a lousy 6 hours of open bar" but I'm not sold on that idea. I would love to hear your ideas!
