The custom jeans and slacks business of Levi Strauss & Co, offered in the 12 Levi's Only Stores (LOS) across the US, grew 28 per cent over the past year, said Jen Crook, manager of mass customisation. The custom program, which Crook characterised as "a drop in the bucket" by comparison with Levi's $5bn business, is currently being fine-tuned for a larger scale roll-out. The retailer may add body scanners at 11 LOSs, one of which has already been in use at the flagship store in San Francisco for two years.
