A dainty azure bow pinned discreetly to the underskirt of your wedding dress is a charming way to honor an age-old tradition. Choose any pretty blue ribbon you like (fabric and trimmings stores offer the widest selection), then tie a small length of it into a tidy bow. Fasten it to the inner layers of your gown or undergarments with a tiny safety pin, and it'll be your little secret: something blue that's hidden from view.
