LONDON — J. JS Lee, Preen by Thornton Bregazzi and Sibling are to stage consumer-facing shows in September, according to the British Fashion Council, organizer of the London Fashion Weekend showcase.

The four-day event will see an estimated 15,000 people cross the Saatchi Gallery’s threshold to take in catwalk shows, industry talks, style presentations and shopping galleries. “London Fashion Weekend continues to see significant growth and it has become increasingly more important for brands and designers to connect directly with their customer,” said Caroline Rush, chief executive officer of the British Fashion Council. “London is the only fashion capital to offer this direct-to-consumer experience and insight into the fashion industry, which is worth 28 billion pounds to the U.K. economy,” she added.

Designers are to parade fall collections, which launched in February during London Fashion Week. “It means that the public can be part of what is usually an industry-only experience,” said Cozette McCreery, cofounder of Sibling, which is to showcase women’s and men’s collections simultaneously.

Hosted by model Jack Guinness and TV presenter Laura Jackson, the biannual event breaks down the barrier between designers and consumers.

Mary Katrantzou, Holly Fulton and Emilia Wickstead are some designers who have previously showed their collections on London Fashion Weekend’s runway.

The event runs from Sept. 22 to 25, with admission prices running from 20 to 200 pounds, or $26 to $260.
