I am trying to make my wedding as affordable to our wedding party as possible. I have two flower girls and two ring bearers, so I also want to make their attire as easy as possible (especially since one of each are my own two kids). My other flower girl is a cousin of my fiance and was in a wedding last year (which my future SIL was also in) so I know that she already has a dress. What I want to know is, would it be acceptable to have her simply re-wear the dress from last year (with some updates to match our color scheme because the other wedding was purple and we are not) and buy my daughter the same dress? I know the girl whose wedding it was and I don't want to upset or offend her either, because she is one of my FSIL's very close friends.
