For MOH duty: Have each bridesmaid, mother, mother-in-law, aunts, etc... create a scrapbook page which includes a letter to the bride along with pictures. This is something she can read while she gets ready. Cute!!
what a fun bachelorette party game: each girl brings a pair of underwear that represents her, and the bride has to guess whose is whose. If she's wrong, she drinks, but if she's right, the girl drinks. And she gets to keep all the knickers!
