This case, "vineyard vines and The Brotherhood of the Traveling Pants," introduces students to a unique partnership in the social media advertising world. Preppy clothing powerhouse vineyard vines had a history of interacting with its customers by featuring user-generated content in its catalogs and on its website and decided to continue this tradition on social media by partnering with a group of fans called The Brotherhood of the Traveling Pants. This successful and authentic social media marketing campaign resulted in increased sales for vineyard vines and influencer status for the members of The Brotherhood. At the end of the campaign, the vineyard vines marketing team is left debating how to grow its social media presence through partnerships. The case has been used as part of a social media marketing course and would be effective in any undergraduate- or graduate-level marketing course.
