Selfridges is changing shape with the unveiling of the Body Studio, a 37,000-square-foot space dedicated to women of various sizes and figures – and with more than clothing on offer. The store's largest-ever department is all about off-duty dressing and stocks lingerie, swimwear, pyjamas and high-performance sports gear. It also has a café, courtesy of Hemsley and Hemsley, sister chefs who push organic greens and proteins, and a Daniel Galvin hair salon with 28 stations, two beauty rooms and a private VIP area.

The department is on Selfridges' Floor Three, located above the Shoe Galleries and connected to them by an escalator. Skylights and picture windows overlooking an interior garden are part of the design intended to help assuage shoppers' anxieties about dressing. It was created by the Shanghai-based architects Neri and Hu, whose past projects include Lane Crawford's Lab and London's Pollen Street Social restaurant.

This is the first major unveiling in Selfridges' 300 million pounds, ($428 million) five-year redevelopment project that was revealed two years ago.
