I've been watching a lot of classic movies lately, and "Roman Holiday" got me all a-twitter for some fun wedding inspiration. You could use vintage postcards for wedding invitations and table cards.
Ride away from the chapel on a Vespa and toss a gorgeous bouquet of pale flowers.
The best part of an Italian inspired wedding is, of course, the food. I know that Italian wedding soup is more of an Italian-American tradition, but why not? It's delish. Serve mounds of gelato and Italian wedding cake for dessert.
