A great way to involve your wedding party is to let them choose their own dress. A easy way to do this is once you have decided on your colors visit the paint store. Once there you can find your color and since it is a paint store it will have the family colors with it. You can give each of your bridesmaids one and no matter how far away everyone lives none of dresses will clash! You may want to set a length guideline if you are having a more formal wedding or if you have a preference.
