Hello,
I was recently in a friends wedding in LA where the MOH sat us down and said, I priced out the venue we're having the shower and it'll be $17/head, the guest list is 55-60 ppl so with decor and the cake, centerpieces for the tables etc, it will probably cost around $1200-1500 total for the shower.  So with so many girls, we'll call it $250/bridesmaid.We were all too stunned to speak and went along with it. 
I do not want to do that to my future sister in law and my cousins and my childhood friend. So I'm not demanding anything and I'm thrilled each want to be in my wedding. I have offered to help with costs for most.
I'm trying to give them a lot of freedom on their attire to help make everything more affordable. In my culture, focus isnt not on these things, too.
