It's the first time we've allowed people behind the scenes, which I'm excited about. It's another way to become a bit more personal," Mary-Kate told USA Today. "We're all growing up. The brand, my sister and I, the customers, the retailers it's nice to be able to allow them to see the brand grow in a more accessible way."

The sisters are intent on letting their products speak for themselves, and the range will show off their signature styles to maximum impact. The collection is the most elevated yet and based around striking silhouettes.

"We wanted it to be a little more feminine and a little more lady in a way, but wanted to do constructed, so it's a little more modern," Mary-Kate said. "We wanted to offer the great suiting we've always had, and the tailoring. With the soft dresses, there's a lot of form-fitting and sexy ..."

The stars clothes are worn by celebrities such as Lauren Hutton and Charlize Theron, and he pair can work from 10am until 11pm daily on their designs.

They are continuing to grow the range and soon hope to expand into handbags.

"We definitely look at this brand as a lifestyle luxury brand," Mary-Kate said.

"It takes two-and-a-half days to do one jacket. It's all handmade," said Ashley. "Those are the things we love doing. It's the attention to detail." (C) Cover Media
