It’s a wedding day disaster on the next Vanderpump Rules.

“Everything is perfect,” Katie says. “Almost.”
When it comes time for the 29-year-old bride to get dressed for the big day, she learns her custom gown no longer fits.
“I feel just a sharp pinch, something jabbing into my side,” Katie explains. “They told me at the last fitting that they were going to put boning in, but this is painful.”
“Maybe tacos and margaritas the night before you’re supposed to slip into a form-fitting wedding dress is not the best idea,” she adds.
