I am paying for my bridesmaid's hair but cannot afford to pay for their makeup. I thought this was fine until my MOH told me she wants to wear RED lipstick. My summer wedding is yellow and green, and I am worried she will look clownish next to all my other bridesmaids who have agreed to go in a more natural direction. I also think we will look like a stoplight if anyone wears red. I tried talking about it to her politely, but I don't want her showing up the day of the wedding with red and me having to cause a scene to have her take it off. How do I handle this politely, while still making it very clear that red lipstick is simply not an option?
