I'm not sure if this is done or how it would even look.  I  am having a matron of honor and 2 brides maids.  They are all different sizes and have different tastes.  I know normally the matron can wear a diffent shade of the same dress.  I was thinking of letting them all pic out the dress (same color and length).  Has anyone ever seen or heard of this being done?  Groom is not in favor.
