Bridesmaid gifts are especially important because you have asked the bridesmaids to share your day, and this will be an acknowledgement of your friendship.
Each wedding has its own flavor, and you have already made decisions about what yours will be like. Your bridesmaid gifts will reflect that image, too, while retaining a glimpse of their individual personalities.
Let's say you have a healthy budget, and a lot of bridesmaids. You might want to give everybody a similar gift, such as a beach bag, (perhaps filled with soaps and fragrances) and then add something more individualized that will reflect the intimacy and the separate levels of commitment that they have made to your wedding.
