The last time we left The Bachelor Sean Lowe, he had just gotten down on one knee in Thailand during season seventeen while proposing to graphic designer, Catherine Giudici. Fast-forward to today, and the soon-to-be Mrs. Lowe will be walking down the aisle towards her groom during ABC's two-hour special event, The Bachelor: Sean and Catherine's Wedding.

Not only does this wedding mark the fourth couple in the franchise's history to make it down the aisle—see Trista Rehn and Ryan Sutter, Jason Mesnick and Molly Malaney, and Ashley Hebert and J.P. Rosenberg—but Sean and Catherine's wedding will also be the very firstBachelor wedding to air live on television. To see these two make history and exchange their "I do's," make sure you tune in to ABC tonight at 8/7c. Till then, relive the best fashion moments from Sean Lowe's The Bachelor in our gallery.
