Ten ambitious fashionistas vie for a dream job working for fashion royalty Diane von Furstenberg as she launches the search for a Global Brand Ambassador. Their first task is to represent DVF at the 5th Annual DVF Awards at the United Nations.

DVF's Brand Ambassador program is underway and the girls are tasked with inspiring next season's collection. But after a photo shoot turns into an all-out cat fight, Diane questions whether she should terminate the entire program.

Jealousy ensues when Diane singles out one of the girls to attend the CFDA Awards while the rest are left behind to work on a press presentation. The girls first time in front of the press proves to be a bigger challenge than anticipated.

The ambassador candidates must organize an exclusive luncheon to debut a new DVF line, but a rivalry between two girls and a night of partying threatens to ruin the event.

An argument breaks out during a retail assignment and the fighting escalates as the girls are challenged to create a social media campaign. But when the girls bring their hostilities into DVF's office, Diane is forced to make some unexpected decisions.

The Ambassador candidates rush out to the Hamptons to style celebs and VIPs, but when one of the girls gets sassy with the DVF team, her position in the program is jeopardized. What starts as a casual house party ends in a total disaster.

Stakes are high when the girls style themselves for a photo shoot and interview with InStyle magazine. Diane says goodbye to one hopeful and reveals the girls' wrap dress designs.

The season finale culminates with DVF's exclusive New York Fashion Week event where everything the girls have worked toward is put to the test. Diane must decide who the new Brand Ambassador will be.
