Kristen and Troy's wedding was beautifully unique in that they decided to base their day around a theme. Vintage Hollywood was tastefully designed into the fabric of the day. Through their decor, their big band, and the newsies passing out the "papes" (which happened to be ceremony programs), the theme made the day so special for Kristen, Troy and their guests.
You may notice the gnome in the film. Kristen and Troy regularly travel with the gnome and he makes his way into many of their photos, so of course, he had to be a part of the film as well!
