special occasion shoes

hello all! my cousin is getting married (hasn’t even set a date but im panicking) and i’m the maid of honour. i hate that one of the things im most worried about is what shoes to wear!! i want to prepare a list of shoe options ahead of time before it’s too late so i’ve come to ask for help
for reference i’m 24 F, and my club foot is my left foot which is about a size 6.5, and my right foot is a size 8
i have struggled wearing sandals in the past because my club foot just slides around, gets tons of blisters, and still doesn’t feel supported. i have custom orthotics that i wear everyday with my usual sneakers/boots but realize i can’t exactly use those in special occasion shoes. i’ve tried to wear flats and am so uncomfortable and feel/know im walking weird lol
i would appreciate any and all advice!
