Men's wear retailer and hire shop Moss Bros has warned that its new look stores and ranges will take longer than expected to produce profitable results. The group, which is still in the red, does not expect to return to profit until the end of 2002. It made pre-tax losses of £3.9million for the first six months of the year compared with a previous £16.2million loss, while turnover fell from £71.6million to £68.6million.
