High street fashion chain River Island has been going back to the future this year with 50s glamour styles and a vintage denim look. The company hopes to bring a new gloss to its profit figures after enjoying a huge sales boost for very little return. Accounts filed by the family-owned Lewis Trust Group showed retail turnover up 7.3 per cent at GBP406m, but pre-tax profits were fractionally reduced at GBP55.7m in the year to December.
