Feeling tired of life on the road, Lily is quitting touring in favour of a quieter life, and to realise another dream - to open a vintage shop.

The series begins backstage at The O2 Arena on the last night of Lily's tour as she prepares to begin a new chapter in her life. Along with her half-sister Sarah (a total business novice) Lily plans on making couture and vintage pieces available to those who may not be able to afford such luxury items in an innovative clothes store where customers can hire or buy one-off designer garments.

They set out transforming Lily's office into the base for their business. But all they have is the name - Lucy in Disguise - and an idea.

To make up for their lack of experience and transform their dream for the shop into a viable business Sarah and Lily hire Jess Morris as their brand director. With 15 years in the fashion industry under her belt Jess has worked for the likes of Agent Provocateur and Vivienne Westwood, and it's her job to help them find the right shop in the right place with the right stock.

While Lily is easily carried away spending her hard earned money on amazing one off items, Sarah is tasked with sorting out the company finances as she undergoes a crash course in business management to try and devise a budget for the project.

They start splashing the cash on couture fashion for stock but receive some home truths about their plans from retail guru Mary Portas after a focus group is unsure about the shop's concept and prices.

Tensions between the sisters are running high as Sarah tries to take financial control of the business. Lily talks openly about the rift in their relationship when they were younger, and reveals how her slim figure the press raved about in 2009 was the result of an unhealthy relationship with food.
