I decided to post this here because a lot of you have far more experience being in weddings than I do and I want honest opinions.
My sisters are both in my WP and we are all tall girls so we have large feet. My wedding is a very formal evening wedding (Black Tie Optional) and the bridesmaid dresses are formal so I thought the shoes should be too. I even suggested that if they didn't want to wear heels they could go for a satin ballet flat. Now I'm being told that one sister doesn't like ballet flats and refuses to wear them, she would prefer to be in flip flops. The other sister has said that unless she gets to wear flip flops she will be taking her shoes off as soon as she gets to the reception and she'll be barefoot if she has to be. I have looked at all sorts of flip flops and I don't really feel they match how formal the dresses are. I also worry about the amount of noise flip flops make. The church we are having the ceremony at is very strict and I don't want to be disrespectful. I wouldn't even consider flip flops appropriate for Sunday services. So, am I being unreasonable by asking my sister to find shoes that are formal and not flip flops? Suggestions and advice welcome! Thanks in advance!
