There is another way to allow maids some say in their dress style, without sacrificing the overall look. If you choose the manufacturer, the color, the fabric, and what length you want, you can allow your girls to choose whatever style they want within those parameters, without sacrificing uniformity.
These dresses are all by Bill Levkoff, in his European Satin fabric in "Euro Fuschia" and "Euro Black". All the girls are in different styles, but it's still obvious they are all members of the bridal party.
