Free touches that add something special to a wedding

Julie Zanfagna Roland, who was married on the beach in Narragansett, R.I., two years ago, remembers her favorite touch from a friend’s wedding. “She asked everyone to write their all-time favorite dance song on the RSVP card,’’ Roland recalls. “The DJ used the responses to make the song list.’’ Yin recalls one reception in which a “courageous groom serenaded his wife on the dance floor, playing the guitar and singing their song.’’ Kerry Epstein, a Boston wardrobe stylist, recently helped organize a bachelorette party for her sister, Lauren, in which all the bridesmaids learned the steps from the music video for Beyoncè’s “Single Ladies.’’ The girls then showed off their mastery of choreography at the wedding.
