Returning clothes is expensive for retailers and irritating for customers. Up to 50% of clothes bought online are returned, which costs companies millions in handling and postage. Offline, retailers have been experiencing growing numbers of 'wardrobers' - shoppers who buy, wear and return clothes.

Fashion retailer Bonobos is establishing itself as a pioneer in taking online retail offline. Its Guide Stores combine personal service with the efficiency of online ordering - and now they’re blending the digital and physical further by adding SELFY mirrors to fitting rooms.
