Hi Everyone, My chief bridesmaid (and sister) wants to be a little different from everyone else in the bridal party..to show that she is cheif.. Anyone have any ideas that can make her stand out as cheif/maid of honour from the other bridesmaids without differing too much from the theme colours? Thanks! X picture is of the dress it's mink.. Flowers are Cadbury purple, Ivory and lilac and i have already ordered them all the same. I'd appreciate any ideas! Gem x
