So, I'm having a pretty traditional wedding. My BMs are all wearing the same dress, althought I made sure that everyone was comfortable with the cut/color/length, and we went through five different options until everyone agreed. I really don't mind; I want everyone to be comfortable first, and I told them they're comfort comes before my "vision". That said, one of my BMs might be taking that a bit too far.
As I said, our wedding is pretty traditional, as far as traditions go in our families. The girls are all walking down the aisle one-by-one, and I'm coming down to "Here Comes the Bride". I brought up to one of my BMs that I was thinking of "Rainbow Connection" for the BM processional. She has been the one that I feel like I have had to accomodate the most for. She says she won't wear heels, which is fine, and won't wear strapless, also fine. She tried to insist that the BMs wear long dresses, and I told her no because it's a summer wedding and I think that shorter dresses look nice, and she literally threw a fit. I didn't back down, and she eventually agreed to the short dresses. I don't know if it makes a difference, but I'm paying for the dresses so that my BMs (all students) don't have to make such a big purchase just for my wedding.
Anyway, this BM told me that she wanted to walk down the aisle with one of the groomsmen, because she thinks it's awkward to walk down the aisle alone with nothing else but a bouquet. She is a performer, so it's not like she hates attention (not that she's an attention-hog either), she just says she thinks it's weird looking and awkward. I need to say that there are few things that I have held on to from being a little girl and planning my PPD when I was ten, but having my bridesmaids go down the aisle one by one is one of the things I have. I don't want to change that because one out of my four BMs thinks its awkward.
My question is, what do I say to that? I don't want her to continuously get her way all the time, but I don't want to come off as a total 'zilla. She's the youngest of my FI's family, and always gets her way. How can I tell a spoilt child (she's in her early twenties, in case you want to know) no?
