Harry Potter is one of the most popular franchises of all time. Needless to say, there are plenty of people centering their weddings around it. Of course, you need to be a real fan to want to base your wedding around a book, but the Harry Potter franchise has no shortage of fans!
For the wedding dress, a lot of people seem to be choosing a sexy, tea-length strapless dress number with an A-line skirt and a pattern that looks a bit like black birds' wings.
For a Harry Potter wedding, rustic and winky decor is preferred to traditional or classic decor. Wooden wands make fun party favors, as well as invitations that put each guest in a different "house". You could also use animal designs--cats, owls, frogs, or any other animal featured prominently in the books. Even serve Bertie Bott's Jelly Beans and chocolate frogs! Get creative!
