I have 5 bridesmaids of all different sizes. I decided on a color (a very dark plum) which is only available by Bill Levkoff, a chiffon fabric, and floor length dresses allowing the maids to get the style of their choice. My two plus size maids (my sisters) were not happy with not being able to try dresses on in their size. They were able to try dresses on at Davids Bridal to get an idea of style they were comfortable in. Now they are complaining about the designer not being plus size friendly and having size charts that are less friendly in proportions than others. Dresses can be ordered in sizes 0 to 30. The size chart proportioms are within a half inch of Davids Bridal. Some dresses are available up to a size 14-16 to try in store. The two maids are larger than these sizes and will not order a dress without being able to try in their size. One of my maids has purchased a dress in the designer, color, fabric, and length of choice. Any advice on how to proceed would be helpful.
