Hayley is trying to make it as a clothing designer. When her best friend, who follows the reality show about a bachelor who has to choose a bride, sees the chance to apply to be on the show, she brings Hayley along for moral support. It doesn't fare any better that both she and Hayley are accepted (even though Hayley didn't apply). However, Hayley allows herself to be persuaded as it could give her a chance to launch her clothing designs.
Even though I hate reality shows, this worked as a romantic movie despite the theme but not all the way.
