bridesmaids for my wedding?

do you have to have bridesmaids? me and my fiancé want to get married next year and I really have no girl friends. I have a sister and I don’t trust her and she is a toxic person so I don’t want her in my wedding. not even sure I want to invite her.

is that required? he has groomsmen or at least his brother so Idk if that would be weird for me to not have a maid of honor or any of that but I really have no one.
