So I am having a casual beach wedding in florida November 1, 2014. My colors are navy and coral. Originally I wanted all my bridesmaids to wear the same navy floor length strapless chiffon dress. However, recently my moh suggested that they wear short dresses to keep it more casual and to keep the sand off their dresses. I completely understand her point, however I have 6 girls to think of and they are all different shapes and sizes. What should I do? And which type of dress should I choose??
