Choose a color that reflects your theme and complements your dress. Get input from your bridesmaids-especially if they will be paying for their own dresses. (Remember, as the bride, you have ultimate veto power).
Consider the figures and skin color of your bridesmaids and try to choose a style that is flattering to everyone. Many brides are offering their bridesmaids several styles in the same fabric and color so they can choose a style that suits them best.
Shop around to get the best deal and don't forget the evening wear departments of fine clothing stores as an alternative to bridal shops-especially if you have a smaller wedding party. You're more likely to find a sale price at these stores.
