Simply send in pictures/representations of your desired colors and a For Her And For Him stylist will find the closest match. You will then emailed pictures of the custom color along with a custom swatch code to use when ordering your bridesmaids dresses.
If you want to be extra sure that the custom color choice matches your needs, you also have the option to order a fabric swatch. Double confirmation never hurts! Definitely impressed with this concept as it allows you the ability to ensure that your bridesmaids' looks flow nicely with your chosen color scheme.
