In the middle of the melee, Carson meets Kathryn and joins her wedding dress search party, called Team New Mexico.

After two and a half hours and a dozen dresses, Kathryn finally picks a winner. Carson says her Reem Acra gown would have cost $5,000 to $6,000—but Kathryn got it for just $699.

When Kathryn's father, Ed, gets a sneak preview of what his daughter will look when he walks her down the aisle, he's left on the verge of tears. "It's the first time I really realized it's going to happen," he says.
