I told my daughter to do her own makeup because we don’t have $75 for her to pay a stylist and my daughter in law is demanding a stylist ?

It's customary for the bride's family to pay for the wedding so I'm not sure why the bride is demanding that you pay for anything. 

They pay for a stylist, or the money gets taken away from some thing else, or they can borrow money from some one else to pay for the stylist. Tell them you can't put any more money into their wedding. 

Weddings are a stressful time for everyone involved in the planning and festivities so stay calm and respect each other since this is a normal part of life.  It's common for the bridal party to have hair and makeup done professionally even if she is high maintenance so don't get too stressed try to make the best of things.  Good Luck and God Bless you and congratulations.

Odd to me that your son's fiance is REQUIRING anyone to do anything.

You need to put future (future as in not even a family member yet and she is calling/demanding the shots already) tosh, tell her to pay.  I had my hair and make-up done by a stylist for my daughters wedding and had to re-do both.

Pretty elementary proplem solving...

Anyone who wants to hire a stylist can book and pay for their own appointment.

Here are three easy steps to Saying" NO".

1) mirror the request

2) saying" no "nicely

3) suggest an alternative

So, in your case:

1) I understand you want tolooknice at the wedding

2) However, We did not budget for a stylist and therefore, we will not be hiring one

3) But, don't let that stop you from hiring one for yourself. Perhaps you can ask the venue for recommendations.

Repeat to all who expect you to foot the bill for a stylist.

If the son's fiance requires her to get it professionally done, they can pay for it...

Learn to say no. You can tell your son, we won’t be paying for a professional to do our make up. If your bride wants to pay, we will happily comply. Or your son can pay the fee for his sister.

Don’t argue. Learn to say sorry no. We are at the limited for our budget,  we will not be spending anymore money.  

Unfortunately, their wedding ..  their choice and being an attendant in a wedding isn't cheap.  Being a bridesmaid is a good $500 investment and if it's a destination wedding then throw the expenses of a vacation on top of that.

If she's requiring hair/makeup/nails to be professionally done then she should actually be paying for it but she may not realize that.  If she can't afford it, then she should realize maybe others can't either.

This where you talk to your son and your son talks to her but it's unlikely to resolve anything and may cause additional issues.

In my own wedding, I didn't want anyone to have any type of financial issues paying for something so everything was a wedding expense to me, without my wedding these weren't expenses that would have existed for them.  We paid all of our attendants expenses (attire, shoes, hair, etc) and for a couple of them that included travel because they lived in another state.  However we could afford to do so, not everyone can.

If your son has picked out someone who is high maintenance that is okay because that is his choice.

Also assuming your daughter is an adult here she can address this herself.

If she does end up having to do the professional makeup, I'd highly recommend doing a trial too.  My SIL was one of those demanding bougie brides who also required this and I decided to do a trial of the makeup job first and I'm glad I did because I ended up being allergic to the first makeup they used.  It was one of those before/after makeover pictures where the before picture was way better.

Pick your battles.

Yeah....so I fall into the category of people who think if a Bridezilla wants to dictate every aspect of her wedding down to requiring a professional makeup artist, then she should be the one paying for all of it. I don’t think you have an obligation to give in to her demands, especially considering they are having a destination wedding that you are traveling for. You simply need to have a conversation with your son and his bride to be where you tell them in a loving way “We have reached our budget for what we can spend on your wedding. If it is vitally important to you for makeup to be professionally done, you will need to provide that, as we do not have that expense in our budget.” And then be ready to hold firm, because it may get dramatic and emotional. But the bottom line here is that you should not be going broke for your son’s wedding. Assuming he is an adult, he and his bride should be paying for their own party.
