I would really like to hire a hair/make-up artist for my wedding, as I am hopelessly incompetent when it comes to styling myself. I had not planned to hire someone for my entire party because I'm not asking any of the BMs to do anything specific, and while it would be nice to pamper them anyway I simply can't afford it.
However, two of the BMs, friend and FSIL, have approached me individually a few different times to ask if I was hiring someone. They would really like to use whoever I hire. They are willing to pay for it themselves, and I think(?) I'm within etiquette to let them given that it's 100% optional and 100% their idea (honestly, they were the ones who sold me on hiring my own).
The problem is, I haven't yet approached MOH, my younger sister. My guess is that she will not be interested because she does not need it and because my mother STRONGLY disapproves of me hiring someone even for myself (she said it would be "self-centered"). My parents are financing her participation in the wedding, so I don't believe finances would be a consideration other than on principle. It does not matter to me whether MOH uses the make-up artist or not, but that does of course mean that MOH will be left out while the rest of us are getting our hair and make-up done on the day.
Do I have any obligations here -- to not hire the professional? To not hire someone onsite? To step up and book a package so that there's no question of MOH being left out? I will need to know this before I book, because paying for everyone is not an option -- if that's the obligation, then I will just have to suck it up and style myself. I realize that it's possible to DIY and that this is kind of a luxurious expense, but I am just so awful at doing my own hair and make-up and I'd really like to look nice.
