WIBTA if you let this be a bigger problem. if anything why not think of it like Halloween dress up? Trying something new and having a blast with it? Me and my sister both weren’t into makeup when we were ask to be bridesmaids and I had my makeup done by someone at a mall and tbh I look weird( my bad for picking someone who does it too dramatic lol)but I just let it go ( when you are new to makeup you don’t realize how much idealism there is on how you THINK it should look but it shows Less dramatic when you take pictures!) since you will get it professionally done why not watch how she does it and see what you like about it and not like you know? My sister hated the feeling and the process of it but with much encouragement she and I got over it this hill and enjoy the experience ! You don’t have to wear it all day too! you are definitely right on that! Just wear it for the picture and if it still too much you can discreetly wash it off just a few pictures shouldn’t ruin your time :D ! Why not ask for a natural make up look! Be daring and try things girl!
