This weekend I had my Hair and make up Trial. It turned out beautifully! I loved it so much. I went the whole day with it and noticed it may need to be tighter or more hairspray. Anyway the next day I decided to get more information on moving forward. I asked my bridesmaids if they would like to go through this place as well so they can write up the contract(they would be responsible for paying. I wish I could but it isn't in the budget). I got my answers pretty easy. Somehow the topic became, how do you want our hair to be done. It was a good question, because I haven't thought about it just yet. One of my bridesmaid brought up a good point which I fully agreed on that since my hair is up maybe theirs should be down or half up and I was like 100% on it because it would look more uniform since my bridesmaids will be having alternating colors and styles. So in the group chat my FSIL said she started to plan ahead and planned on wearing her hair up, because she doesn't want her hair to stick to her neck. I told her I understand but I will be the only one in the bridal party that has their hair up. (through the night Im pretty sure all of our hairs will need touch ups and we have a bridal suite upstairs of our venue where the girls can privately fix up). She then Private messaged me on IG and sent me an half updo that looked pretty but too bridal and I told her this is nice but maybe something with more loose curls. She then told her mom what I said i am assuming, because shortly after FH mom texted him saying something like "when you have time I would like to talk to you". We immediately felt that's what it was for. So this morning we found out yes she was complaining to her mom about it. FH stood up for me and said that the other bridesmaids are understanding that their hair will need to be down or half up, so she will just need to understand this is not her wedding. He said he told his mom that when its her wedding she can have her way. About an hour ago FSIL texted FH a long message starting with "youre a horrible selfish brother..." I don't know the rest, but it really bothered me. I feel like she is making a huge deal out of this. I am letting them pretty much pick their dress style as long as the fabric is the same, within color palette, and does not have a slit.
I understand they are paying for it, but I feel like they should be able to find a hairstyle that they like that is within what I would like the bridesmaids to look like and also similar to the other bridesmaids.
Am I being controlling?
