Bridesmaid refusing to wear certain colours
Quick question, are you paying for the BM’s dresses?
If you are, it’s not down to her to dictate the colour scheme of your Wedding. Obviously you want your BM’s to feel comfortable and nice on the day but all this fuss over a colour is a little bit silly. If she continues to be demanding and difficult i’d just say to her that the colour scheme for the entire Wedding is blush and therefore the dresses need to fit with this. If she doesn’t want to agree to this then she can’t be a BM but that will be down to her.
