The pop star and her sister Sarah Owen - who recently opened vintage clothing store Lucy in Disguise in London together - were both really keen to get involved in the industry, and made the decision to open a shop so they could be creative without having to make their own items.
She said: "I love vintage clothing and I felt like we could highlight how brilliant vintage shopping can be.
"Neither myself nor my sister are designers, but we love fashion and working with vintage allows us to be creative and as involved with the clothes as we can be."
The 25-year-old singer - who is currently pregnant with her first child with her boyfriend Sam Cooper - also insists she isn`t worried about working with her sibling and believes they will make a success of the business.
She said: "We came up with the concept together. I love working with my sister - trust is a big thing for me when choosing who to work with and that isn`t an issue between us.
"We trust each other completely and feel very luck to have each other."
