The Bridesmaid Wore Stains by Conda V. Douglas
Poor Kat. Her best friend Debbie insists Kathleen-the-Klutz wear her ugliest bridesmaid's dress to Debbie's wedding. Worse, Kat must bring a plus one! Much worse, if Kat can't get up the courage to ask her new boyfriend, Gary, Debbie threatens to set Kat up with Kat's childhood nemesis, Luke, as a substitute.
Can Kat avoid staining her new relationship with Gary long enough to see Debbie down the aisle, or will her trademark clumsiness condemn her to a bridesmaid's worst nightmare?
