Not only are designer brands losing some of their appeal but the power of fashion and apparel labels and logos declines over aging market segments a new study has found. More than 7,500 apparel customers were interviewed as part of a recent survey conducted by Brand Keys, a New York marketing research consultancy. The results showed that logos and labels were less important to 57 per cent of respondents; while 10 per cent thought the symbols were more important than previously.
