Over a year ago, I asked my fiance's half brother and sister if they wanted to be in the wedding party and both said no. My FMIL just called and said that she wants them both in the wedding party now, and she doesn't care what they do, she just wants them in. I have 2 months till I get married. I'm not sure if they will have enough time to get the dress and suit to be a BM/GM. What other rolls can they fill to be part of the wedding ceremony? Side note: they are 18 and 20 years old so I think ring bearer and flower girl are out..
