This makes all the difference.
I suspect most of us voted from what was implied in your title and opening post.
My feeling is that the Bride pays for anything they are insisting on having.
Usually that will be the dress. Some brides want matching hair and / or make up, and those brides should therefore pay for that. Otherwise, then no, if the bride is happy for bridesmaids to look the way they do the rest of their lives, then she isn't expected to pay for them to have a MUA. Same with shoes, jewellery, accessories, and money wasted on matching robes for getting ready etc. If people can wear what they already have, then there is no bill for the bride, but if she wants something to 'match' then it is down to her to pay for it.
Going back to change my vote now.
