So I am having my hair stylist come in and do my hair on wedding day. I am also trying to find someone who can come and do my makeup as well. I am not requiring that any of my bridesmaids have their hair or makeup professionally done. I told them it is their choice how their hair and makeup is done. I feel if any of my girls choose to take advantage of these services, it would be a nice gesture if I paid for it. My question is if worse comes to worse and I cannot pay for everyones, is it wrong for them to pay for the services themselves since I am making them optional?
