For our wedding, we have a 10-person bridal party. Of those 10, four are married and will obviously be bringing their spouse to the wedding. I am not opposed to allowing the single members of our BP to bring dates as a general rule, but my FSIL, who is a BM, wants to bring a date more than anything, mostly because she just broke up with her BF. In her case, she is talking about bringing her ex-BF's best friend, which we feel would just end up turning into her very own bitch-fest. The other option she has mentioned is to bring a close friend of her's (female), with which we would be fine. Really, she wants to get back together with her (huge ass) ex and hopes that it happens before the wedding. We DEFINITELY don't want that to happen.... Honestly, we'd rather she just go stag and have fun with the other BMs and family and friends and such. We don't want to have our wedding album, especially candids, turn into a commemoration of her bad decisions, if she chooses to bring some random date, ex's BF, or, God-forbid, the ex. So, the question is, can we stipulate who she can bring or suggest to her that she not bring a date? We don't want her to feel like we are forbidding her from doing so and prevent her from having a good time, but we feel like she'd probably enjoy herself more if she isn't worrying about her date, since she'll be tied up with BM duties the whole day.... Do we have to give all the bridal party plus ones?
