I think it depends on if you're requiring them to do their makeup/hair. In that case, I think the bride should cover. This is especially true if they had to buy their own gowns, too (I've been a MOH twice and financially it was tough for me at the time).
If they're opting to, I think it's a bit more in the grey.
My wife's bridesmaids all paid for their own dresses (they all had different styles but in the same color) but I seem to remember that my wife covered the makeup costs (it was done at our home). Matron of honor did my wife's hair and the other bridesmaids had their hair done at salons, so they covered the expense. I think it's a pretty mixed bag of possibilities when it comes to that.
As a gift for my Girls I am paying for their hair so they all match. But Makeup I am giving them the option to splurge and get it done or to do it themselves. They all chose to have it done so they don't have to stress.
I don’t have a bridal party (too much headache for me personally), anyways if I were to have a bridal party, I would pay for their dresses and make up/hair. I don’t like putting pressure on people to obtain X and Y.
I am paying for my Mothers and MIL hair (they don’t want their make up done) and they are wearing whatever they want. Less headache for me.
I am not sure yet what I am going to do, I have paid for their dresses but they are paying for their alterations (which will be minimal). My FH and I will make that decision closer to our October wedding date but with enough time to ensure they can work it in to their budget.
Everyone’s budget and situation is different and I have seen it happen both ways. I’m personally paying for my girls to have theirs done as well as their hair as my budget allows for it. Everyone is different and either way is perfect
It's honestly up to each person I think. But also if its in your budget. You dont have to pay for everyone if you dont want to. Since either only had my moh standing up for me I paid for her makeup. We had my aunt who is a hair stylist do our hair so it didn't cost us anything
I treated my nieces and mom to hair and make up because I was able to make it happen in the budget but if I had a large bridal party, I might have had to ask them to do it and treat them somehow in a different way.
