I recently had a BM back out of the wedding, and after FI and I discussed, I am going to ask my cousin to step in and take her place. How do I ask her without her feeling that she's "second best"? I know we don't have to ask someone to fill in, but both FI and I do not like the idea of uneven sides in BP, so that's not an option. She is under 18, and would need some financial assistance from her parents for the dress, so I could use help with ideas for asking her, and for asking her parents. Thanks!
