"Resale Royalty" chronicles the story of Sue McCarthy and her daughters, Diane and Laura, who own and operate one of the best resale stores in the country. This mother-daughter trio work to bring designer brands at affordable prices to their fashion savvy clientele. With more than 25 years of experience in the resale business, Sue has big plans for the future, but she needs her daughters - who have very different approaches to management - to help with the expanding empire. From spectacular closet buys of posh St. Louis socialites to exclusive shopping tours across the country, "Resale Royalty" is an exploration of high-end fashion events, insider trends, designer insight and the highs-and-lows associated with a demanding business overseen by an eccentric staff, who are also family.
