Hi need some advice, I get on really well with my fiancee's sister and love her to bits, however she is a very awkward person she's not good in social situations at all and can be very fussy. I want to ask her to be my bridesmaid however i'm stressing about if she says yes as I know it will be hell trying to find a dress that she will be comfortable in and even then she won't agree to have her hair or makeup done on the wedding day and won't stay with me and the other bridesmaids the night before so I won't be able to get her ready. Should I ask my mother in law to be to help her out on the big day?
